CATO supplies Methyl 6-methyl-2-(thiophene-2-carboxamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (CAS 329923-64-0), a certified reference material (molecular formula C16H17NO3S2, MW 335.44 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 6-methyl-2-(thiophene-2-carboxamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 335.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), Methyl 6-methyl-2-(thiophene-2-carboxamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate 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.
