Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Ethyl 5-amino-4-chloro-1-(4-methoxyphenyl)-1H-pyrazole-3-carboxylate (CAS 1427014-18-3) is a high-purity analytical reference standard with the molecular formula C13H14ClN3O3 and a molecular weight of 295.72 g/mol.
The molecular framework of Ethyl 5-amino-4-chloro-1-(4-methoxyphenyl)-1H-pyrazole-3-carboxylate (C13H14ClN3O3) is characterized by a nitrogen-containing heterocyclic scaffold, 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. 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 analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
