Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
643767-79-7 Phenyl-sulfonium Chloride Phenyl-sulfoniumylidene Chloride (CAS 643767-79-7) is a high-purity analytical reference standard with the molecular formula C6H7SCl and a molecular weight of 146.63 g/mol.
Based on its molecular formula C6H7SCl, 643767-79-7 Phenyl-sulfonium Chloride Phenyl-sulfoniumylidene Chloride contains sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 146.63 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).
As a certified reference material (CRM), 643767-79-7 Phenyl-sulfonium Chloride Phenyl-sulfoniumylidene 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.
