Chemical Structure
Description
The occurrence of Benzene, 1,3-diisocyanato-2-methyl-, polymer with 1,6-diisocyanatohexane and 2,4-diisocyanato-1-methylbenzene is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Benzene, 1,3-diisocyanato-2-methyl-, polymer with 1,6-diisocyanatohexane and 2,4-diisocyanato-1-methylbenzene (CAS 86220-50-0), molecular formula C9H6N2O2C8H12N2O2 and molecular weight 342.35 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Benzene, 1,3-diisocyanato-2-methyl-, polymer with 1,6-diisocyanatohexane and 2,4-diisocyanato-1-methylbenzene (C9H6N2O2C8H12N2O2) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 342.35 g/mol, it falls into the moderately-high-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
