Chemical Structure
Description
The molecular framework of 2-Oxepanone, polymer with 1,6-hexanediol and 1,1'-methylenebis[4-isocyanatobenzene] (C15H10N2O2C6H14O2C6H10O2) 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).
2-Oxepanone, polymer with 1,6-hexanediol and 1,1'-methylenebis[4-isocyanatobenzene] (CAS 68938-85-2), molecular formula C15H10N2O2C6H14O2C6H10O2 and molecular weight 482.58 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-Oxepanone, polymer with 1,6-hexanediol and 1,1'-methylenebis[4-isocyanatobenzene] 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.
