Compared with other compounds in its class, the molecular weight of 356.42 g/mol gives Salcaprozate Impurity N1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Salcaprozate Impurity N1 (CAS 20073-95-4), a pharmacopoeial impurity reference standard (molecular formula C20H24N2O4, MW 356.42 g/mol) used for the identification and quantification of trace impurities in APIs.
Salcaprozate Impurity N1 (C20H24N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures Salcaprozate Impurity N1 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.
