Application:
Shanghai Ruifu Chemical Co., Ltd. is the leading manufacturer and supplier of (1R,2R)-(-)-2-Amino-1-(4-nitrophenyl)-1,3-propanediol (CAS: 57794-08-8), also named D-(-)-threo-2-Amino-1-(4-nitrophenyl)-1,3-propanediol with high quality. (1R,2R)-(-)-2-Amino-1-(4-nitrophenyl)-1,3-propanediol (CAS: 57794-08-8) (Chloramphenicol base) is an intermediate for synthesizing Chloramphenicol, a broad spectrum antibiotic agent. Chloramphenicol base is the parent 4-nitrophenylpropylamine formed by the hydrolysis of the dichloroacetamide of chloramphenicol. Chloramphenicol base per se does not work as an antibiotic, however, it plays an important role in the synthesis and antibacterial activities of chloramphenicol and other new generation antibiotics, represented by thiamphenicol and its experimental analogues, bromamphenicol and methamphenicol.
