Chemical Structure
Description
The molecular framework of 2-Cyano-N-(3,4-dimethylphenyl)-3-(3-methoxyphenyl)propanamide (C19H20N2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2-Cyano-N-(3,4-dimethylphenyl)-3-(3-methoxyphenyl)propanamide (CAS 1260914-72-4), molecular formula C19H20N2O2 and molecular weight 308.37 g/mol, is a CATO reference standard with documented purity and traceability.
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), 2-Cyano-N-(3,4-dimethylphenyl)-3-(3-methoxyphenyl)propanamide 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.
