Chemical Structure
Description
The molecular framework of N-(4-(1H-Pyrazol-3-yl)phenyl)-2-(4-(cyanomethoxy)phenyl)acetamide (C19H16N4O2) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
N-(4-(1H-Pyrazol-3-yl)phenyl)-2-(4-(cyanomethoxy)phenyl)acetamide (CAS 1376381-45-1), molecular formula C19H16N4O2 and molecular weight 332.36 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), N-(4-(1H-Pyrazol-3-yl)phenyl)-2-(4-(cyanomethoxy)phenyl)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.
