Information Gain Key Takeaway: As a vital zwitterionic organic compound, 3-Amino-1-Propanesulfonic Acid (also widely recognized as Homotaurine or Tramiprosate, CAS: 3687-18-1) plays a fundamental role in neuropharmacological therapeutics, biological buffering, electroplating additives, and advanced cosmeceutical formulations. Our China-based manufacturing infrastructure guarantees batch-to-batch consistency exceeding 99.5% purity via green catalytic synthesis routes.
3-Amino-1-Propanesulfonic acid possesses the molecular formula C₃H₉NO₃S with a molecular weight of 139.17 g/mol. Its unique structure featuring a terminal primary amine group and a terminal sulfonic acid group separated by a three-carbon aliphatic chain creates a highly polar zwitterionic structure. This architecture grants high solubility in water, structural stability across wide pH windows, and high binding affinity with key biological receptors.
Modern commercial synthesis utilizes catalytic amidation and sulfonation of acrylonitrile or propanesulfone pathways. Gentolex's optimized production process eliminates toxic heavy metal residue risks by leveraging specialized green catalytic hydrogenation techniques. This allows us to scale production up to multi-ton metric quantities while minimizing carbon emissions and meeting ISO 14001 environmental benchmarks.
Our raw material sourcing and manufacturing operational protocols follow international cGMP regulations. Each batch of 3-Amino-1-Propanesulfonic Acid undergoes exhaustive analytical testing via High-Performance Liquid Chromatography (HPLC), Nuclear Magnetic Resonance (NMR), Differential Scanning Calorimetry (DSC), and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for trace heavy metals.

Gentolex operates an overall factory construction area of 250,000 square meters adhering to international regulatory standards. Our state-of-the-art facilities house multi-purpose reaction suites, automated crystallization systems, cleanroom drying corridors, and computerized batch tracing software designed for large-scale enterprise execution.
Through process intensification, automated chemical processing, and optimized heat exchange systems, our OEM operations achieve significant cost reduction. We pass these savings directly to our global commercial partners, enabling pharmaceutical and chemical brands to enhance their unit margins without compromising analytical purity.
How global enterprises utilize 3-Amino-1-Propanesulfonic acid across diverse technical vertical sectors.
In clinical research, 3-Amino-1-Propanesulfonic Acid (Homotaurine / Tramiprosate) is recognized for its ability to bind selectively to GABA_A receptors and inhibit the aggregation of amyloid-beta (Aβ) peptides into neurotoxic oligomers. Formulators and API manufacturers incorporate our high-purity compound into investigational drugs targeting cognitive maintenance, neurodegenerative disorders, and memory enhancement clinical protocols.
Due to its stable zwitterionic behavior near physiological pH, 3-Amino-1-Propanesulfonic Acid is utilized as a biological buffer in specialized diagnostic reagents and cell culture systems. It helps maintain homeostatic osmotic pressure and stabilizes sensitive enzymes, recombinant proteins, and peptide sequences during bioprocessing operations.
In the high-end personal care and skin chemistry markets, Homotaurine acts as an effective cellular osmotic balance protector and anti-glycation agent. Skincare manufacturers integrate it into specialized anti-wrinkle serums, dermal repair gels, and hydrating creams to improve skin barrier homeostasis and defend cellular structures against environmental oxidative stress.
The chemical electrodeposition industry utilizes 3-Amino-1-Propanesulfonic Acid as a complexing additive and grain refiner in modern electroplating baths. Its sulfonic acid functionality aids in micro-level leveling during metal deposition, preventing dendrite formation and improving surface adhesion in printed circuit board (PCB) and semiconductor lead-frame production.
Organic synthesis laboratories utilize this functionalized amino-sulfonic acid molecule as a strategic building block for sulfa-derivatized peptides, zwitterionic polymers, and surfactant chemical families. Its bifunctional structure permits selective derivatization at either the nitrogen or sulfur terminal points.
In modern agrochemical R&D, 3-Amino-1-Propanesulfonic acid derivatives serve as systemic transport enhancers and osmoprotectants for crops subjected to severe drought or high-salinity soil conditions, elevating plant stress resistance metrics.
