Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 3-(2-chlorobenzamido)benzofuran-2-carboxylate.
Ethyl 3-(2-chlorobenzamido)benzofuran-2-carboxylate (CAS 477498-96-7) is a high-purity analytical reference standard with the molecular formula C18H14ClNO4 and a molecular weight of 343.76 g/mol.
Structurally, Ethyl 3-(2-chlorobenzamido)benzofuran-2-carboxylate (C18H14ClNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 343.76 g/mol, it falls into the moderately-high-molecular-weight range. 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), Ethyl 3-(2-chlorobenzamido)benzofuran-2-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.
