Chloramphenicol

CAS 56-75-7Cl2CHCONHCH(CH2OH)CH(OH)C6H4NO2Biochemicals & Reagents

Chloramphenicol (CAS 56-75-7) is a synthetic broad-spectrum antibiotic, historically derived from *Streptomyces venezuelae*. With a molecular weight of 323.13 g/mol, it is known for its bacteriostatic and bactericidal properties. Primarily utilised in molecular biology for bacterial selection at concentrations of 10-20 μg/mL and as a selective agent for antibiotic-resistance genes in transformed cells. It is also listed as suitable for plant cell culture.
