Description
CATO supplies 3-[1-(3-Aminophenyl)-3-tert-Butyl-1H-pyrazol-5-yl]-1-(2,3-dichlorophenyl)urea (CAS 227622-98-2), a certified reference material (molecular formula C20H21Cl2N5O, MW 418.32 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-[1-(3-Aminophenyl)-3-tert-Butyl-1H-pyrazol-5-yl]-1-(2,3-dichlorophenyl)urea is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 418.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3-[1-(3-Aminophenyl)-3-tert-Butyl-1H-pyrazol-5-yl]-1-(2,3-dichlorophenyl)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.
