19436-52-3 | N-Acetyl-D-alanine

✅ Pharmaceutical Intermediate

 1. Peptide Drug Synthesis: Chiral building block for manufacturing D-amino acid-containing peptides (e.g., antimicrobial peptides, opioid receptor agonists, and protease inhibitors). The acetyl group protects the amino terminal during peptide coupling, preventing side reactions.

2. Antibiotic Production: Used in the synthesis of semi-synthetic β-lactam antibiotics (e.g., modified penicillins and cephalosporins) to improve antibacterial spectrum and stability against β-lactamases.

3. CNS Drug R&D: Applied in the preparation of D-amino acid derivatives targeting NMDA receptors, which are potential treatments for schizophrenia, Alzheimer's disease, and ischemic stroke.

✅ Food & Feed Industry

1. Flavor Enhancer: As a chiral additive to improve the taste and aroma of processed foods (e.g., beverages, dairy products, and savory snacks); enhances umami flavor without increasing sodium content.

2. Feed Supplement: Added to animal feed to promote growth and improve nutrient utilization; the D-configuration is resistant to enzymatic degradation in the gut, extending its bioavailability.

✅ Biomedical Research

1. Chiral Resolution Reagent: Used to separate racemic amino acid mixtures via HPLC or capillary electrophoresis, due to its specific chiral recognition ability.

2. Enzyme Substrate: Serves as a substrate for studying the specificity of aminoacylases, proteases, and other enzymes involved in amino acid metabolism.

✅ Material Science

1. Chiral Polymer Monomer: Polymerized with diols or diacids to prepare optically active polyamides, which are used in chiral stationary phases for chromatography, nonlinear optical materials, and biodegradable plastics.

✅ Lab/Research Grade Packaging

- Sealed amber glass vials with Teflon-lined screw caps, specifications: 5 g, 25 g,  100 g; vacuum-sealed to prevent moisture absorption and racemization; labeled with purity (≥99.0%), optical purity (ee ≥99.5%), batch number, and storage conditions

.✅ Industrial/Production Grade Packaging

1. 25 kg/50 kg Fiber Drums: With double polyethylene (PE) inner liners for moisture-proof and leak-proof protection; drum labels include CAS number, product name, net weight, hazard warnings (slightly irritant to skin/eyes), and transportation marks.

2. 1000 kg Bulk Bags (FIBC): For large-volume shipments; equipped with lifting loops and PE liners; suitable for automated production line integration.

3. Customized Packaging: 1 kg/5 kg aluminum foil vacuum bags for small-batch commercial sales; compliant with ICH Q7 GMP standards for pharmaceutical applications.
