methyl 2-(thietan-3-ylidene)acetate CAS 61890-04-8

Description

The occurrence of methyl 2-(thietan-3-ylidene)acetate 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.

CATO supplies methyl 2-(thietan-3-ylidene)acetate (CAS 61890-04-8), a certified reference material (molecular formula C6H8O2S, MW 144.19 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, methyl 2-(thietan-3-ylidene)acetate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), methyl 2-(thietan-3-ylidene)acetate 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.
