Dihydro-2H-thiopyran-3(4H)-one CAS 19090-03-0

Description

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

Dihydro-2H-thiopyran-3(4H)-one (CAS 19090-03-0), molecular formula C5H8OS and molecular weight 116.18 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C5H8OS, Dihydro-2H-thiopyran-3(4H)-one contains sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 116.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
