Chemical Structure

1,1-Dioxothiolane-3-thiol CAS 52513-18-5 chemical structure

Description

The occurrence of 1,1-Dioxothiolane-3-thiol is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,1-Dioxothiolane-3-thiol (CAS 52513-18-5), molecular formula C4H8O2S2 and molecular weight 152.24 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-Dioxothiolane-3-thiol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 152.24 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-Dioxothiolane-3-thiol 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.
