1-Isocyanato-2-methylprop-1-ene CAS 28705-49-9

Description

The occurrence of 1-Isocyanato-2-methylprop-1-ene is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Isocyanato-2-methylprop-1-ene (CAS 28705-49-9), molecular formula C5H7NO and molecular weight 97.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, 1-Isocyanato-2-methylprop-1-ene is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 97.12 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.

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.
