pH ：5.0～7.5

Loss on drying: ≤ 0.5%

Absorbance: 280 ㎜ wavelength shall not exceed 0.10; 264 ㎜ wavelength should be 0.80 ~ 0.88

Penicillin polymer: calculated by peak area according to external standard method, the polymer containing penicillin shall not exceed 0.08% based on penicillin

Physicochemical properties: white crystalline powder, odorless, or slightly specific odor, with a decomposition point of 215 ℃. It is very soluble in water, ethanol, fat oil and liquid paraffin. It has hygroscopicity, and can make penicillin in the presence of acid, alkali, oxidant, penicillinase, etc β- The lactam ring opens and fails. Crystalline penicillin sodium salt is relatively stable. Its aqueous solution is easy to fail at room temperature and cannot be boiled for disinfection. Penicillin G sodium solution can be stored for one week at 2 ~ 8 ℃ after filtration and sterilization, longer at -20 ℃ and only for 3 days at 37 ℃

Purpose: biochemical research. Inhibit bacterial cell wall synthesis. Antibacterial spectrum: gram positive bacteria.

Storage: 2 ~ 8 ℃
