Lincomycin EP impurity B

CAS: 37744-65-3

Lincomycin impurity B is a chemical substance which is the result of the metabolism of lincomycin. It is found in the urine and feces of patients who have taken lincomycin orally. Lincomycin impurity B has been detected in various commercial formulations of lincomycin, but its concentration varies with different batches. The HPLC standard purity for lincomycin impurity B is up to 99%. Lincomycin impurity B can be used as an analytical standard for HPLC analysis and as an API impurity in drug development. It also may be used as a research metabolite or pharmacopoeia reference material.
