Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Nicotinamide impurity 22 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Nicotinamide impurity 22 (CAS CATO-C4X-200022) is a certified pharmaceutical impurity reference standard with the molecular formula C17H17N5O3 and a molecular weight of 339.35 g/mol.
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 Nicotinamide impurity 22 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.
