Description
CATO manufactures 3,5-Dimethyl-2-phenylthiophene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
3,5-Dimethyl-2-phenylthiophene (CAS 57021-49-5), molecular formula C12H12S and molecular weight 188.29 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H12S, 3,5-Dimethyl-2-phenylthiophene contains sulfur-containing functionality, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 188.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
