Chemical Structure

n-[2-(1h-1,3-benzodiazol-2-yl)ethyl]-3-methylbenzamide CAS 303991-77-7 chemical structure

Description

n-[2-(1h-1,3-benzodiazol-2-yl)ethyl]-3-methylbenzamide (CAS 303991-77-7), molecular formula C17H17N3O and molecular weight 279.34 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, n-[2-(1h-1,3-benzodiazol-2-yl)ethyl]-3-methylbenzamide is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 279.34 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.

As a certified reference material (CRM), n-[2-(1h-1,3-benzodiazol-2-yl)ethyl]-3-methylbenzamide 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.
