Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1-dioxido-2,3-dihydrothien-3-yl methyl ether.
1,1-dioxido-2,3-dihydrothien-3-yl methyl ether (CAS 7353-90-4), molecular formula C5H8O3S and molecular weight 148.18 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 1,1-dioxido-2,3-dihydrothien-3-yl methyl ether is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.18 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.
As a certified reference material (CRM), 1,1-dioxido-2,3-dihydrothien-3-yl methyl ether 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.
