Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 249.93 g/mol gives 3,4,5-Trichlorothiophene-2-carbonylchloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3,4,5-Trichlorothiophene-2-carbonylchloride (CAS 24422-15-9), molecular formula C5Cl4OS and molecular weight 249.93 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,4,5-Trichlorothiophene-2-carbonylchloride (C5Cl4OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 3,4,5-Trichlorothiophene-2-carbonylchloride 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.
