Chemical Structure

Hexanedioic acid, polymer with 1,2-ethanediol and 1,1'-methylenebis[4-isocyanatobenzene] CAS 25931-01-5 chemical structure

Description

Hexanedioic acid, polymer with 1,2-ethanediol and 1,1'-methylenebis[4-isocyanatobenzene] (C15H10N2O2C6H10O4C2H6O2) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Hexanedioic acid, polymer with 1,2-ethanediol and 1,1'-methylenebis[4-isocyanatobenzene] (CAS 25931-01-5), molecular formula C15H10N2O2C6H10O4C2H6O2 and molecular weight 458.47 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.
