Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Hexanedioic acid, polymer with hexanediol and 1,1'-methylenebis[4-isocyanatocyclohexane] (CAS 67859-52-3), a certified reference material (molecular formula C15H22N2O2C6H10O4C6H14O2, MW 526.67 g/mol) for analytical method development and quality control.
The molecular framework of Hexanedioic acid, polymer with hexanediol and 1,1'-methylenebis[4-isocyanatocyclohexane] (C15H22N2O2C6H10O4C6H14O2) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), Hexanedioic acid, polymer with hexanediol and 1,1'-methylenebis[4-isocyanatocyclohexane] 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.
