Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Chloro-5-methoxy-2-(4-methoxyphenyl)-2H-indazole (CAS 848142-56-3), molecular formula C15H13ClN2O2 and molecular weight 288.73 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Chloro-5-methoxy-2-(4-methoxyphenyl)-2H-indazole (C15H13ClN2O2) 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 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.
CATO manufactures 3-Chloro-5-methoxy-2-(4-methoxyphenyl)-2H-indazole 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.
