一水阿奇霉素 (CAS No.121470-24-4)
- 物化性质
- 白色或类白色结晶性粉末，微有引湿性。本品几乎不溶于水，易溶于甲醇、乙醇、丙酮等有机溶剂。在pH 6.0~8.0的缓冲液中溶解度较低，在酸性条件下溶解度增加。熔点约113~115℃（分解），需避光、密封、干燥处保存。
- 技术参数
- 含量（以无水物计）≥98.0%，按干燥品计算 干燥失重 ≤6.0%（一水合物理论含水量约2.4%） 炽灼残渣 ≤0.2% 重金属 ≤20ppm
English description（英文原文，共 1393 字符）
Product Name:Azithromycin Monohydrate
English Name:Azithromycin Monohydrate
CAS No.:121470-24-4
Aliases:Azithromycin monohydrate, 9-Deoxy-9a-aza-9a-methyl-9a-homoerythromycin A monohydrate
Molecular Formula:C38H74N2O13·H2O
Physical Properties:White or almost white crystalline powder, slightly hygroscopic. Practically insoluble in water, freely soluble in methanol, ethanol, acetone and other organic solvents. Low solubility in pH 6.0-8.0 buffer solutions, while solubility increases under acidic conditions. Melting point approximately 113-115°C (decomposes). Store protected from light, in a tightly closed container, in a dry place.
Uses:Azithromycin is a second-generation macrolide antibiotic that exerts bacteriostatic effects by inhibiting bacterial protein synthesis. Clinically, it is used for the treatment of respiratory tract infections, skin and soft tissue infections, urogenital infections caused by susceptible organisms. It has a broad antibacterial spectrum with good activity against Gram-positive bacteria, some Gram-negative bacteria and atypical pathogens.
Technical Specifications:
Assay (on anhydrous basis) ≥98.0%, calculated on the dried basis
Loss on drying ≤6.0% (theoretical water content of monohydrate is approximately 2.4%)
Residue on ignition ≤0.2%
Heavy metals ≤20ppm
Related substances: maximum individual impurity ≤1.0%, total impurities ≤3.0%
