Chemical Structure
Description
CATO supplies 5-chlorothiophene-3-carbonitrile (CAS 1108712-56-6), a certified reference material (molecular formula C5H6ClNS, MW 147.63 g/mol) for analytical method development and quality control.
Structurally, 5-chlorothiophene-3-carbonitrile (C5H6ClNS) contains a nitrile group, sulfur-containing functionality, chlorine substitution. 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 147.63 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.
As a certified reference material (CRM), 5-chlorothiophene-3-carbonitrile 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.
