Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-[(5-Chloro-1,3-dimethyl-1H-pyrazol-4-yl)formamido]-N-(4-methoxyphenyl)-2-phenylacetamide (CAS 1031210-14-6) is a high-purity analytical reference standard with the molecular formula C21H21ClN4O3 and a molecular weight of 412.87 g/mol.
The molecular framework of 2-[(5-Chloro-1,3-dimethyl-1H-pyrazol-4-yl)formamido]-N-(4-methoxyphenyl)-2-phenylacetamide (C21H21ClN4O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 2-[(5-Chloro-1,3-dimethyl-1H-pyrazol-4-yl)formamido]-N-(4-methoxyphenyl)-2-phenylacetamide 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.
