Description
As a certified reference material (CRM), Potassium Benzenethiolate 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.
Potassium Benzenethiolate (CAS 3111-52-2), molecular formula C6H5SK and molecular weight 148.26 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H5SK, Potassium Benzenethiolate contains sulfur-containing functionality, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 148.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
