Chemical Structure

n-Butane-1,1,2,2,3,3,4,4,4-d CAS 97565-89-4 chemical structure

Description

Structurally, n-Butane-1,1,2,2,3,3,4,4,4-d (C4HD9) contains deuterium isotope labeling. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 67.18 g/mol, it falls into the low-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).

n-Butane-1,1,2,2,3,3,4,4,4-d (CAS 97565-89-4) is a high-purity analytical reference standard with the molecular formula C4HD9 and a molecular weight of 67.18 g/mol.

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.
