Description
CATO manufactures Dimemorfan Phosphate Impurity 9 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 Dimemorfan Phosphate Impurity 9 (CAS CATO-C4X-33589), a pharmacopoeial impurity reference standard (molecular formula C18H25NH3O4P, MW 353.40 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Dimemorfan Phosphate Impurity 9 (C18H25NH3O4P) is characterized by a steroid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
