Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 5-(2-chloro-phenyl)-3-cyclopropyl-4,5-dihydro-1H-pyrazole 928264-58-8 (CAS 928264-58-8), a certified reference material (molecular formula C12H13ClN2, MW 220.70 g/mol) for analytical method development and quality control.
The molecular framework of 5-(2-chloro-phenyl)-3-cyclopropyl-4,5-dihydro-1H-pyrazole 928264-58-8 (C12H13ClN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
