Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Brexpiprazole Impurity 70.
Brexpiprazole Impurity 70 (CAS 6940-78-9) is a certified pharmaceutical impurity reference standard with the molecular formula C4H8BrCl and a molecular weight of 171.46 g/mol.
Owing to chlorine/bromine substitution, Brexpiprazole Impurity 70 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 171.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Brexpiprazole Impurity 70 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.
