Chemical Structure
Description
CATO manufactures Ilaprazole Impurity 166 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.
CATO supplies Ilaprazole Impurity 166 (CAS 1015057-65-4), a pharmacopoeial impurity reference standard (molecular formula C8H9Cl2NOHCl, MW 242.52 g/mol) used for the identification and quantification of trace impurities in APIs.
Ilaprazole Impurity 166 (C8H9Cl2NOHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
