Chemical Structure
Description
As a certified reference material (CRM), Diethyl 5-acetamido-3-methylthiophene-2,4-dicarboxylate 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.
CATO supplies Diethyl 5-acetamido-3-methylthiophene-2,4-dicarboxylate (CAS 4815-41-2), a certified reference material (molecular formula C13H17NO5S, MW 299.34 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, Diethyl 5-acetamido-3-methylthiophene-2,4-dicarboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 299.34 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.
