Chemical Structure

1-Phenyl-3-(5-phenyl-1-(2,4,6-trichlorophenyl)-1H-pyrazol-4-yl)urea CAS 477713-89-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Phenyl-3-(5-phenyl-1-(2,4,6-trichlorophenyl)-1H-pyrazol-4-yl)urea.

CATO supplies 1-Phenyl-3-(5-phenyl-1-(2,4,6-trichlorophenyl)-1H-pyrazol-4-yl)urea (CAS 477713-89-6), a certified reference material (molecular formula C22H15Cl3N4O, MW 457.74 g/mol) for analytical method development and quality control.

The molecular framework of 1-Phenyl-3-(5-phenyl-1-(2,4,6-trichlorophenyl)-1H-pyrazol-4-yl)urea (C22H15Cl3N4O) 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. 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.

CATO manufactures 1-Phenyl-3-(5-phenyl-1-(2,4,6-trichlorophenyl)-1H-pyrazol-4-yl)urea 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.
