Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Rifamycin Impurity 15.
Rifamycin Impurity 15 (CAS CATO-C4X-200413) is a certified pharmaceutical impurity reference standard with the molecular formula C49H59N6O11 and a molecular weight of 908.03 g/mol.
Structurally, Rifamycin Impurity 15 (C49H59N6O11) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 23.5, corresponding to approximately 23 ring(s) or double-bond equivalent(s). With a molecular weight of 908.03 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Rifamycin Impurity 15 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
