Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Erlotinib Impurity 70 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 343.33 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 Erlotinib Impurity 70 (CAS CATO-C4X-106970), a pharmacopoeial impurity reference standard (molecular formula C15H21NO8, MW 343.33 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 Erlotinib 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.
