Chloramphenicol is a synthetic antibiotic, isolated from strains of
Streptomyces venezuelae. It is widely used against gram-positive and gram-negative bacteria, and is used mainly for ophthalmic and veterinary purposes
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
Mode of Action:Chloramphenicol inhibits bacterial protein synthesis by blocking the peptidyl transferase step by binding to the 50S ribosomal subunit and preventing attachment of aminoacyl tRNA to the ribosome. It also inhibits mitochondrial and chloroplast protein synthesis and ribosomal formation of (p)ppGpp, de-pressing rRNA transcription
Mode of Resistance:Use of chloramphenicol acetyltransferase will acetylate the product and inactivate it.
Antimicrobial Spectrum: This is a broad spectrum antibiotic against gram-positive and gram-negative bacteria, and is used mainly for ophthalmic and veterinary purposes.
Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to pharmacopeia primary standards.
Stock solutions can be prepared directly in the vial at any recommended concentration. A solution at 50 mg/mL in ethanol yields a clear, very faint, yellow solution. Degradation of chloramphenicol in aqueous solution is catalyzed by general acids and bases. This rate of degradation is independent of the ionic strength and pH.
This Certified Reference Material (CRM) is produced and certified in accordance with
ISO 17034 and
ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
