Description
CATO manufactures 4,4-Dimethyl-1-phenyl-1,4-dihydropyrimidine-2-thiol 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.
4,4-Dimethyl-1-phenyl-1,4-dihydropyrimidine-2-thiol (CAS 146496-45-9), molecular formula C12H14N2S and molecular weight 218.32 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 4,4-Dimethyl-1-phenyl-1,4-dihydropyrimidine-2-thiol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 218.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
