1,2,3-Propanetriol, polymer with 1,3-diisocyanatomethylbenzene and 2,2'-[(1-methylethylidene)bis(4,1-phenyleneoxymethylene)]bis[oxirane] (CAS 71701-22-9) is a high-purity analytical reference standard with the molecular formula C21H24O4C9H6N2O2C3H8O3 and a molecular weight of 606.67 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1,2,3-Propanetriol, polymer with 1,3-diisocyanatomethylbenzene and 2,2'-[(1-methylethylidene)bis(4,1-phenyleneoxymethylene)]bis[oxirane] is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 606.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
