2-Chloro-5-(chloromethyl)thiophene CAS 23784-96-5

Description

Compared with other compounds in its class, the molecular weight of 167.06 g/mol gives 2-Chloro-5-(chloromethyl)thiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Chloro-5-(chloromethyl)thiophene (CAS 23784-96-5), a certified reference material (molecular formula C5H4Cl2S, MW 167.06 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, chlorine substitution, 2-Chloro-5-(chloromethyl)thiophene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 167.06 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).

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
