Physically, D-Glutamine appears as a white to off-white crystalline powder or granular solid. It has a melting point of approximately 185-189℃ (decomposition) and is highly soluble in water, forming a clear and stable aqueous solution, while it is slightly soluble in methanol and ethanol, and insoluble in non-polar solvents. It is optically active, with a specific rotation [α]²⁰/D of +6.5° to +10.5° (in water, c=2). 흡습성이 낮고 적절하게 보관하면 상온, 상압에서도 안정하여 취급, 보관, 제제화가 용이합니다.
In chiral catalysis, it is used as a chiral ligand to promote asymmetric reactions, improving the efficiency and enantioselectivity of organic synthesis. Additionally, it is used as a food additive and nutritional supplement in specific scenarios. 안전 측면에서 일반적으로 정상적인 취급 시 안전하고(GRAS) 무독성이며 자극이 없는 것으로 인식됩니다. 가수분해 및 분해를 방지하기 위해 강한 산화제, 습기 및 고온을 피하고 2~8℃의 서늘하고 건조하고 어두운 환경에 밀봉하여 보관해야 합니다. With its unique chiral properties and versatile applications, it is an indispensable raw material in chiral chemistry and pharmaceutical research.
