Chemical Structure

6-Fluoro-3-methyl-1-benzothiophene-2-sulfonyl chloride CAS 1421602-19-8 chemical structure

Description

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

CATO supplies 6-Fluoro-3-methyl-1-benzothiophene-2-sulfonyl chloride (CAS 1421602-19-8), a certified reference material (molecular formula C9H6ClFO2S2, MW 264.72 g/mol) for analytical method development and quality control.

Structurally, 6-Fluoro-3-methyl-1-benzothiophene-2-sulfonyl chloride (C9H6ClFO2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 264.72 g/mol, it falls into the medium-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).

As a certified reference material (CRM), 6-Fluoro-3-methyl-1-benzothiophene-2-sulfonyl chloride 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.
