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 Cimetidine EP Impurity J 2HBr.
Cimetidine EP Impurity J 2HBr (CAS 38603-73-5) is a certified pharmaceutical impurity reference standard with the molecular formula C7H13N3SHBr and a molecular weight of 252.17 g/mol.
Owing to a nitrile group, sulfur-containing functionality, bromine substitution, Cimetidine EP Impurity J 2HBr is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 252.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Cimetidine EP Impurity J 2HBr 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.
