Description
CATO supplies Methyl 3-[4-([1,1-biphenyl]-4-ylcarbonyl)-1H-1,2,3-triazol-1-yl]-2-thiophenecarboxylate (CAS 439111-70-3), a certified reference material (molecular formula C21H15N3O3S, MW 389.43 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 3-[4-([1,1-biphenyl]-4-ylcarbonyl)-1H-1,2,3-triazol-1-yl]-2-thiophenecarboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 389.43 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.
CATO manufactures Methyl 3-[4-([1,1-biphenyl]-4-ylcarbonyl)-1H-1,2,3-triazol-1-yl]-2-thiophenecarboxylate 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.
