Shanghai Ruifu Chemical Co., Ltd. is the leading manufacturer and supplier of Chloramphenicol (CAS: 56-75-7) with high quality. Chloramphenicol (CAS: 56-75-7), also known as chlornitromycin, is a broad-spectrum, bacteriostatic antibiotic derived from Streptomyces venezuelae. It is first isolated from cultures of Streptomyces venequelae in 1947 but now produced synthetically. The synthetic product is racemic, also called synthomycin. Syntomycin is a mixture of chloramphenicol L-isomer and d-isomer. Because of dextroisomer antibacterial effect, the effect of synthomycin is only half of the natural products. It has a relatively simple structure and was the first broad-spectrum antibiotic to be discovered. It is effective against several gram-positive and gram-negative bacteria and commonly used in researching protein synthesis and to select for chloramphenicol-resistant transformed cells or the bacterial CAT gene.
