Chemical Structure
Description
Hexamethylene Diisocyanate Biuret Trimer (CAS 4035-89-6) is a high-purity analytical reference standard with the molecular formula C23H38N6O5 and a molecular weight of 478.59 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Hexamethylene Diisocyanate Biuret Trimer is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 478.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Hexamethylene Diisocyanate Biuret Trimer under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
