Description
As a certified reference material (CRM), N-(5-Methylpyridin-2-yl)chromane-3-carboxamide 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.
N-(5-Methylpyridin-2-yl)chromane-3-carboxamide (CAS 1057940-71-2), molecular formula C16H16N2O2 and molecular weight 268.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(5-Methylpyridin-2-yl)chromane-3-carboxamide (C16H16N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
