7-氨基头孢子烷酸

7-氨基头孢子烷酸

别名：7-氨基头孢烷酸;7-氨基头孢菌酸;7-氨基头孢霉烷酸;7-氨基-3-[(乙酰氧)甲基]-8-氧代-5-硫杂-1-氮杂二环[4,2,0]-2-烯-2-羧酸；7-ACA

CAS: 957-68-6

分子式：C₁₀H₁₂N₂O₅S

分子量：272.27

EINECS: 213-485-0

含量：≥97%

性状：白色至米黄色结晶粉末

包装：25KG/纸板桶

作用：用作医药中间体，主要用于合成头孢菌素的起始原料。7-ACA是头孢菌素（β内酰胺类）抗生素中间体。生产过程是通过生物发酵、化学提炼制取头孢菌C，再由头孢菌C化学裂解或酶解成7-ACA。头孢菌素类抗生素作用是抑制细胞壁的合成，而人体细胞无细胞壁，故具优良的选择性，安全性大，杀菌力强，是目前临床上最好的一类抗生素。

 

7-Aminocephalosporanic acid

​​Synonyms：(6R,7S)-3-(Acetyloxymethyl)-7-amino-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid；7-ACA

CAS: 957-68-6

MF: C₁₀H₁₂N₂O₅S

MW: 272.27

EINECS: 213-485-0

Assay: ≥97%

Chemical Properties：Off-white to beige crystalline powder

Package：25KG/ Cardboard drum

Usage：Used as pharmaceutical intermediates, starting materials for synthetic cephalosporin. The 7-ACA is the (β-lactam) antibiotics of cephalosporin intermediates. The production process is taken through biological fermentation, chemical refining system cephalosporin C, and then by chemical cleavage or enzymatic hydrolysis of cephalosporin C into 7-ACA. Cephalosporins role is to inhibit cell wall synthesis, human cells without cell walls, so with excellent selectivity, safety, the strong bactericidal current clinical best class of antibiotics.
