Description
As a certified reference material (CRM), 3,4 Dichloro 2-thiophene 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.
3,4 Dichloro 2-thiophene carbonyl chloride (CAS 1446470-85-4), molecular formula C5HCl3OS and molecular weight 215.48 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5HCl3OS, 3,4 Dichloro 2-thiophene carbonyl chloride contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 215.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
