Description

Compared with other compounds in its class, the molecular weight of 255.72 g/mol gives 4-Chloro-5-((p-tolylthio)methyl)isoxazol-3(2H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Chloro-5-((p-tolylthio)methyl)isoxazol-3(2H)-one (CAS 89661-15-4), molecular formula C11H10ClNO2S and molecular weight 255.72 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Chloro-5-((p-tolylthio)methyl)isoxazol-3(2H)-one (C11H10ClNO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 4-Chloro-5-((p-tolylthio)methyl)isoxazol-3(2H)-one 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.
