Explore our high-purity batch-certified active pharmaceutical ingredients, synthetic peptides, and advanced chemical intermediates for global B2B procurement.
An authoritative technical breakdown of Tianeptine salt variants, industrial synthesis routes, and global B2B procurement benchmarks.
Tianeptine (7-[(3-chloro-611-dihydro-55-dioxodibenzo[c,f][1,2]thiazepin-11-yl)amino]heptanoic acid) represents a novel structural class of neuroactive compounds. Unlike traditional tricyclic compounds, Tianeptine acts as a selective serotonin reuptake enhancer (SSRE) and a full agonist at the μ-opioid receptor (MOR) while modulating AMPA and NMDA glutamatergic pathways.
When sourcing from wholesale Tianeptine factories, global buyers must navigate three core crystalline forms, each tailored for distinct analytical, scientific, and formulation requirements:
Commercial-scale production of Tianeptine active ingredients requires rigorous multi-step synthetic organic chemistry. Leading Chinese manufacturing plants utilize optimized alkylation of dibenzo[c,f][1,2]thiazepine 5,5-dioxide intermediates with ethyl 7-bromoheptanoate in the presence of strong inorganic bases.
Subsequent basic hydrolysis yields the free acid compound, followed by precise salt formation under strictly monitored thermal and pH conditions. Crystalline phase purity, solvent residue removal (acetonitrile, ethanol, and toluene), and heavy metal catalysis removal (palladium/platinum controls) are executed under stringent batch monitoring.
Technical E-E-A-T Benchmark: Industrial buyers should always mandate Nuclear Magnetic Resonance (1H-NMR), High-Performance Liquid Chromatography (HPLC), and Mass Spectrometry (MS) verification from manufacturing suppliers to confirm polymorph stability and complete residual solvent evacuation below ICH limits.
| Chemical Form | CAS Registry No. | Solubility Profile | Hygroscopicity Level | Primary B2B Application |
|---|---|---|---|---|
| Tianeptine Sodium | 30123-17-2 | Freely Soluble in Water / Methanol | High (Deliquescent) | API Manufacturing, Rapid-Release Formulations |
| Tianeptine Sulfate | 1224606-06-7 | Slightly Soluble in Water | Low (Atmospheric Stable) | Extended-Release Research, Stable Blends |
| Tianeptine Free Acid | 66981-73-4 | Practically Insoluble in Water | Very Low | Chemical Intermediate, Custom Synthesis |
| Ethyl Ester Intermediate | 66981-77-8 | Soluble in Organic Solvents | None | Upstream API Synthesis |
Analyzing the macro-economic, chemical infrastructure, and supply chain efficiencies driving global leadership in bulk Tianeptine production.
China maintains the world's most complete chemical supply chain infrastructure. Key precursors such as 5,11-dihydrodibenzo[c,f][1,2]thiazepine derivatives and ethyl 7-bromoheptanoate are produced at scale within synchronized chemical industrial clusters in Shandong, Jiangsu, and Zhejiang provinces. This vertical integration mitigates raw material price volatility and guarantees continuous production runs.
By operating multi-ton reactor columns and automated continuous-flow reactors, specialized Chinese factories achieve dramatic reductions in unit energy consumption and overhead cost. Global buyers benefit from highly competitive wholesale tiered pricing structure without compromising on analytical purity or compliance requirements.
Modern Chinese chemical manufacturers operate under rigorous national environmental enforcement and ISO/cGMP standards. Closed-loop effluent treatment plants (ETPs), zero-liquid discharge systems, and automated real-time quality control ensure operational continuity and compliance with global ESG audit requirements for enterprise buyers.

Navigating complex international trade regulations, customs clearance protocols, and cold-chain/ambient shipping logistics for wholesale bulk purchases.
Enterprise buyers require complete batch documentation prior to dispatch. Standard technical dossiers provided by validated factories include:
Tianeptine export demands specialized logistics expertise to ensure seamless customs clearance in destination markets such as North America, Europe, Latin America, and Africa.
Gentolex leverages established regional offices and fulfillment networks in Mexico and South Africa to offer DDP (Delivered Duty Paid) solutions, discrete double-layered vacuum packing, and localized customs warehousing.
Due to the high hygroscopicity of Tianeptine Sodium, packaging integrity is critical. Factories utilize pharmaceutical-grade aluminum foil bags sealed under inert nitrogen atmospheres, packed within fiber drums containing desiccant silica charges. Storage recommendations dictate controlled temperature (2–8°C or <25°C dry conditions) to prevent moisture degradation.
Exploring the evolution of synthetic neuroactive agents, advanced peptide chemistry, and modern API industrial solutions.
The global chemical market is experiencing a profound paradigm shift towards targeted neuro-protective peptides and selective receptor modulators. Compounds such as Selank Acetate, Semax, BPC-157, and SS-31 are rapidly expanding alongside classical small-molecule APIs like Tianeptine. Contract manufacturers are investing heavily in hybrid synthesis lines capable of producing both solid-phase peptide synthesis (SPPS) and complex heterocyclic organic molecules.
Leading Tianeptine factories are replacing legacy batch processes with automated PAT systems. Real-time near-infrared (NIR) monitoring during crystal precipitation ensures hyper-consistent particle size distribution (PSD) and eliminates batch-to-batch variation, providing international buyers with unparalleled product uniformity.

Expert answers regarding bulk Tianeptine procurement, quality testing, custom synthesis, and international shipping.
Standard high-purity industrial grade Tianeptine Sodium supplied by Gentolex is guaranteed at ≥99.0% purity as assayed by High-Performance Liquid Chromatography (HPLC). For specific analytical reference standards or specialized pharmaceutical applications, purities reaching 99.5% or higher can be supplied upon custom synthesis request.
Tianeptine Sodium is highly hygroscopic and readily absorbs atmospheric ambient moisture, turning sticky if left exposed. Tianeptine Sulfate is a modified non-hygroscopic crystalline form that remains dry and powder-stable under normal relative humidity conditions. This makes Tianeptine Sulfate preferred for dry powder blending and longer ambient warehouse shelf-life.
Every export order includes a batch-specific Certificate of Analysis (COA), Safety Data Sheet (SDS/MSDS), HPLC chromatogram, and FTIR spectrum report. Additional third-party laboratory verification (such as heavy metals, micro-biological limits, or NMR spectra) can be provided upon order confirmation.
In-stock API catalog items are typically dispatched within 48 to 72 hours following payment confirmation. Express air delivery via courier takes approximately 5–9 business days globally. Bulk commercial container loads or regional deliveries serviced via Gentolex regional hubs in Mexico and South Africa follow localized transit timelines.
