Chemical Structure
Description
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, Olanzapine Impurity 40 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies Olanzapine Impurity 40 (CAS 1493-27-2), a pharmacopoeial impurity reference standard (molecular formula C6H4FNO2, MW 141.10 g/mol) used for the identification and quantification of trace impurities in APIs.
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 Olanzapine Impurity 40 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.
