Chemical Structure
Description
The occurrence of 2-Methylthiophene-3-carbonyl chloride is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Methylthiophene-3-carbonyl chloride (CAS 123116-02-9) is a high-purity analytical reference standard with the molecular formula C6H5ClOS and a molecular weight of 160.62 g/mol.
2-Methylthiophene-3-carbonyl chloride (C6H5ClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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), 2-Methylthiophene-3-carbonyl 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.
