1,3-Butadiene-2,3-d2 (gas) (stabilized with hydroquinone) CAS 1983-06-8

Description

The occurrence of 1,3-Butadiene-2,3-d2 (gas) (stabilized with hydroquinone) is closely related to deuterium isotope labeling in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,3-Butadiene-2,3-d2 (gas) (stabilized with hydroquinone) (CAS 1983-06-8), molecular formula C4H4D2 and molecular weight 56.10 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to deuterium isotope labeling, 1,3-Butadiene-2,3-d2 (gas) (stabilized with hydroquinone) is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 56.10 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.
