(E)-(4-Hydroxybut-1-en-1-yl)boronic acid CAS 916673-48-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 115.92 g/mol gives (E)-(4-Hydroxybut-1-en-1-yl)boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(E)-(4-Hydroxybut-1-en-1-yl)boronic acid (CAS 916673-48-8), molecular formula C4H9BO3 and molecular weight 115.92 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (E)-(4-Hydroxybut-1-en-1-yl)boronic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 115.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
