Description

CATO supplies 68870-58-6 8163AE C12H10ClNO3 Methyl 3-(4-chlorophenyl)-5-methylisoxazole-4-carboxylate (CAS 68870-58-6), a certified reference material (molecular formula C12H10ClNO3, MW 251.67 g/mol) for analytical method development and quality control.

The molecular framework of 68870-58-6 8163AE C12H10ClNO3 Methyl 3-(4-chlorophenyl)-5-methylisoxazole-4-carboxylate (C12H10ClNO3) 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.

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 68870-58-6 8163AE C12H10ClNO3 Methyl 3-(4-chlorophenyl)-5-methylisoxazole-4-carboxylate 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.
