Chemical Structure

3-Chlorothiophene CAS 17249-80-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 118.58 g/mol gives 3-Chlorothiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-Chlorothiophene (CAS 17249-80-8), a certified reference material (molecular formula C4H3ClS, MW 118.58 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, chlorine substitution, 3-Chlorothiophene is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 118.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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

As a certified reference material (CRM), 3-Chlorothiophene 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.
