Chemical Structure
Description
Methyl 2-(3-methoxybenzamido)-4-methyl-5-(piperidine-1-carbonyl)thiophene-3-carboxylate (CAS 335407-96-0) is a high-purity analytical reference standard with the molecular formula C21H24N2O5S and a molecular weight of 416.49 g/mol.
The molecular framework of Methyl 2-(3-methoxybenzamido)-4-methyl-5-(piperidine-1-carbonyl)thiophene-3-carboxylate (C21H24N2O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), Methyl 2-(3-methoxybenzamido)-4-methyl-5-(piperidine-1-carbonyl)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.
