Chemical Structure

n-Butylbenzene-2,3,4,5,6-d5 CAS 20329-91-3 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

n-Butylbenzene-2,3,4,5,6-d5 (CAS 20329-91-3) is a high-purity analytical reference standard with the molecular formula C10H9D5 and a molecular weight of 139.25 g/mol.

Owing to deuterium isotope labeling, an aromatic ring system, n-Butylbenzene-2,3,4,5,6-d5 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.25 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.
