Description Product Description The chemical name of chlortetracycline (chlortetracycline) is chlorotetracycline and the chemical formula is C22H23ClN2O8. It is a golden yellow crystalline powder produced by the fermentation of Streptomyces aureofacieus. The fermentation broth is acidified and filtered to obtain a precipitate, which is dissolved in ethanol. The crude product is obtained by acid precipitation, and the hydrochloride crystal is obtained by dissolution and salt formation. The effect and antibacterial spectrum are the same as those of tetracycline, but the adverse reactions are the largest among tetracyclines (chlortetracycline>oxytetracycline>tetracycline). Chlortetracycline is a tetracycline antibiotic, and many rickettsia, mycoplasma, chlamydia, atypical mycobacteria, and spirochetes are sensitive to chlortetracycline. Enterococcus is resistant to it. Over the years, due to the wide application of tetracyclines, common clinical pathogens are highly resistant to chlortetracycline...
