|Product name:||Oxytetracycline Hydrochloride|
|Molecular Formula：||C22H25ClN2O9 |
Oxytetracycline Hydrochloride is a yellow, crystalline powder, hygroscopic. It is freely soluble in water, sparingly soluble in ethanol. Solutions in water become turbid on standing, owing to the precipitation of oxytetracycline.
Oxytetracycline Hydrochloride is a broad-spectrum antibiotic. Its antimicrobial spectrum and principle are basically the same as tetracycline. Oxytetracycline hydrochloride has antimicrobial activity against Gram-positive bacteria, meningococcus, gonococcus and other gram-negative bacteria.
