Application 1: Chiral chemistry research — core reference material for discovery of molecular chirality and spontaneous resolution of enantiomers; standard reagent for chiral separation and stereochemistry research.
Application 2: Pharmaceutical & Food Fields — chelating agent, pH buffering agent and formulation stabilizer for oral liquid preparations, injection excipients and food additives (good biocompatibility).
Application 3: Analytical Chemistry — reference material for ESR/EPR high-dose radiation dosimetry (more sensitive than L-alanine); metal ion sequestering agent for complexometric titration and impurity detection.
Application 4: Electroplating & Surface Treatment — complexing agent for metal electro-deposition (improves uniformity and adhesion of metal coating).
Application 5: Biochemical Research — nutrient component and pH stabilizer in microbial culture medium; additive for protein crystallization. GHS Classification: Not classified as hazardous; mild skin and eye irritant.
Signal Word: None
Handling Precautions: Avoid inhalation of dust and long-term skin contact; wash hands thoroughly after operation; avoid contact with eyes and mucous membranes.
Storage Precautions: Seal and store in a cool, dry, well-ventilated place; keep away from moisture and strong oxidants; tightly seal original packaging after use.
Transport: Non-hazardous goods; no special labeling or transportation restrictions; complies with general chemical transportation specifications.
