Chemical Structure

5,5-Dimethyldihydro-2H-thiopyran-3(4H)-one CAS 18615-62-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,5-Dimethyldihydro-2H-thiopyran-3(4H)-one.

CATO supplies 5,5-Dimethyldihydro-2H-thiopyran-3(4H)-one (CAS 18615-62-8), a certified reference material (molecular formula C7H12OS, MW 144.23 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, 5,5-Dimethyldihydro-2H-thiopyran-3(4H)-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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 5,5-Dimethyldihydro-2H-thiopyran-3(4H)-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.
