Introduction

D-Alanine is the D-enantiomer of L-Alanine, a non-proteinogenic amino acid. It is an essential component in bacterial peptidoglycan, forming D-Ala-D-Ala dipeptides that help maintain cell wall integrity.

Features

Low Moisture
Moisture ≤0.5%, keeps powder free-flowing and easy to store.

Easy Dissolution
Dissolves quickly in water, forming a uniform solution without clumps.

Dust-Free Handling
Compact crystals minimize dust, making handling safer and cleaner.

Long Shelf Life
Remains stable up to 2 years in sealed containers without change in properties.

Customization Services

Purity Options：Provide standard ≥99% or higher purity on request.

Documentation：Customer-specific labels, COA, or compliance certificates provided.

Crystal Form：Adjustable crystal size or shape for flow or dissolution needs.

Applications

Pharmaceuticals:
Chiral intermediate in β-lactam antibiotics (penicillin, cephalosporin) and anticancer drug synthesis.
Essential for enzyme studies and antibiotic resistance research.

Biochemical Research:
Used to study D-alanine dehydrogenase and racemase pathways.
Supports antibiotic mechanism and resistance modeling.

Agriculture & Feed:
Functional feed additive to promote probiotic growth (e.g., Lactobacillus).
Potential plant disease resistance activator (research stage).

Cosmetics (Experimental):
May help regulate skin microbiome by suppressing harmful bacteria (requires clinical validation).

FAQ

Q: Does D-Alanine absorb moisture during handling?

A: No, it is non-hygroscopic and remains free-flowing under normal storage and handling conditions.

Q: Can the crystal shape or size be customized?

A: Yes, we can adjust crystal morphology to improve flow, dissolution, or handling for specific applications.

Q: What is the typical batch size available?

A: We offer flexible batch sizes ranging from small trial quantities to multi-ton bulk orders.

Q: What quality control measures are applied?

A: Each batch undergoes HPLC purity analysis, optical rotation verification, moisture testing, and particle inspection before shipment.

Q: Can you produce higher purity grades for sensitive applications?

A: Yes, we can manufacture D-Alanine with higher purity or tighter optical rotation control for specific technical requirements.

Q: How should D-Alanine be stored?

A: Store in a cool, dry place, sealed from moisture and direct sunlight; avoid prolonged exposure to humid conditions.
