Chemical Structure

2-(thietan-3-ylidene)acetic acid CAS 1934863-13-4 chemical structure

Description

As a certified reference material (CRM), 2-(thietan-3-ylidene)acetic acid 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.

2-(thietan-3-ylidene)acetic acid (CAS 1934863-13-4) is a high-purity analytical reference standard with the molecular formula C5H6O2S and a molecular weight of 130.16 g/mol.

Structurally, 2-(thietan-3-ylidene)acetic acid (C5H6O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 130.16 g/mol, it falls into the low-molecular-weight range. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
