2-(((4-Chlorophenyl)thio)methyl)-5-methoxy-4H-pyran-4-one CAS 100726-56-5

Description

The molecular framework of 2-(((4-Chlorophenyl)thio)methyl)-5-methoxy-4H-pyran-4-one (C13H11ClO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.

2-(((4-Chlorophenyl)thio)methyl)-5-methoxy-4H-pyran-4-one (CAS 100726-56-5) is a high-purity analytical reference standard with the molecular formula C13H11ClO3S and a molecular weight of 282.74 g/mol.

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

As a certified reference material (CRM), 2-(((4-Chlorophenyl)thio)methyl)-5-methoxy-4H-pyran-4-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
