Chemical Structure

3,4-Bis(Hydroxymethyl)thiophene CAS 18354-73-9 chemical structure

Description

3,4-Bis(Hydroxymethyl)thiophene (CAS 18354-73-9), molecular formula C6H8O2S and molecular weight 144.19 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,4-Bis(Hydroxymethyl)thiophene (C6H8O2S) 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 144.19 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).

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), 3,4-Bis(Hydroxymethyl)thiophene 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.
