Chemical Structure
Description
2-Butene-1,1,1,4,4,4-d (CAS 358731-97-2) is a high-purity analytical reference standard with the molecular formula C4H2D6 and a molecular weight of 62.14 g/mol.
Owing to deuterium isotope labeling, 2-Butene-1,1,1,4,4,4-d is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 62.14 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.
