Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,3-Butanediol, polymer with 2,4-diisocyanato-1-methylbenzene and 2-ethyl-2-(hydroxymethyl)-1,3-propanediol (CAS 25087-02-9) is a high-purity analytical reference standard with the molecular formula C9H6N2O2C6H14O3C4H10O2 and a molecular weight of 398.46 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1,3-Butanediol, polymer with 2,4-diisocyanato-1-methylbenzene and 2-ethyl-2-(hydroxymethyl)-1,3-propanediol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.46 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).
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.
