Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(3,4-dimethylphenyl)-2-(2-ethoxy-4-formylphenoxy)acetamide (CAS 433234-26-5), molecular formula C19H21NO4 and molecular weight 327.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(3,4-dimethylphenyl)-2-(2-ethoxy-4-formylphenoxy)acetamide (C19H21NO4) is characterized by a flavonoid core, an amide 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).
As a certified reference material (CRM), N-(3,4-dimethylphenyl)-2-(2-ethoxy-4-formylphenoxy)acetamide 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.
