Description
Compared with other compounds in its class, the molecular weight of 146.59 g/mol gives 3-Chlorothiophene-2-Carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Chlorothiophene-2-Carbaldehyde (CAS 67482-48-8), a certified reference material (molecular formula C5H3ClOS, MW 146.59 g/mol) for analytical method development and quality control.
3-Chlorothiophene-2-Carbaldehyde (C5H3ClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 3-Chlorothiophene-2-Carbaldehyde 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.
