Methylnaltrexone Bromide Impurity 7 CAS CATO-C4X-15217

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methylnaltrexone Bromide Impurity 7.

Methylnaltrexone Bromide Impurity 7 (CAS CATO-C4X-15217) is a certified pharmaceutical impurity reference standard with the molecular formula C21H25NO4 and a molecular weight of 355.43 g/mol.

Based on its molecular formula C21H25NO4, Methylnaltrexone Bromide Impurity 7 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 355.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Methylnaltrexone Bromide Impurity 7 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.
