General Quality Standards
  • *Max1: Max Unknown Purity threshold limit.

  • Alcohol: ≤ 0.5% (All Products)
Purified Water Process (API Standard)

Purified water used in production and equipment cleaning for API is generated from municipal city water. It is processed through multi-stage pre-treatment (multi-media filter, softener, activated carbon filter) and reverse osmosis (RO). Water is continuously circulated at 25±2℃ with a constant flow rate of 1.2 m/s.

Frequently Asked Questions (FAQ)
What are the primary purity levels guaranteed for these D-amino acid derivatives?
Most products strictly meet HPLC purity thresholds of ≥98.0% up to ≥99.5%, with controlled isomer limits kept consistently at or below 0.1% to 0.5%.
What does "*Max1" represent in the quality indicators table?
*Max1 specifies the maximum permitted threshold for any individual unknown impurity identified during analytical testing.
What residual solvent controls are implemented across all products?
All catalog products follow tight solvent limits: Acetic Acid is controlled to ≤0.02%, while Ethyl Acetate and Alcohol levels are maintained at ≤0.5%.
How is purified water quality maintained during API manufacturing?
Water is produced via Reverse Osmosis (RO) following pre-filtration (softeners and activated carbon). It is stored and constantly circulated under controlled parameters (25±2℃, flow velocity of 1.2 m/s).
Why are low isomer impurity levels critical for Fmoc/Boc protected D-amino acids?
Controlling optical and structural isomer impurities ensures high coupling yield, eliminates side reactions, and prevents epimerization during peptide synthesis and API downstream processing.
