Chemical Structure
Description
The molecular framework of 2H-Azepin-2-one, hexahydro-, polymer with 1,3-diisocyanato-2-methylbenzene, 2,4-diisocyanato-1-methylbenzene and 2,2'-oxybis[ethanol] (C9H6N2O2C6H11NOC4H10O3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2H-Azepin-2-one, hexahydro-, polymer with 1,3-diisocyanato-2-methylbenzene, 2,4-diisocyanato-1-methylbenzene and 2,2'-oxybis[ethanol] (CAS 71519-77-2), molecular formula C9H6N2O2C6H11NOC4H10O3 and molecular weight 393.44 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), 2H-Azepin-2-one, hexahydro-, polymer with 1,3-diisocyanato-2-methylbenzene, 2,4-diisocyanato-1-methylbenzene and 2,2'-oxybis[ethanol] 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.
