Description
CATO manufactures 3-(4-Chlorostyryl)-1H-pyrazole 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.
3-(4-Chlorostyryl)-1H-pyrazole (CAS 852691-01-1), molecular formula C11H9ClN2 and molecular weight 204.66 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-Chlorostyryl)-1H-pyrazole (C11H9ClN2) 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. 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.
