Description
Remimazolam Impurity 8 (CAS 1275616-60-8) is a certified pharmaceutical impurity reference standard with the molecular formula C26H31BrN5O6P and a molecular weight of 620.43 g/mol.
Based on its molecular formula C26H31BrN5O6P, Remimazolam Impurity 8 contains a steroid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 620.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Remimazolam Impurity 8 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.
