Chemical Structure
Description
The occurrence of Propa-1,2-dien-1-ylboronic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Propa-1,2-dien-1-ylboronic acid (CAS 83816-41-5), molecular formula C3H5BO2 and molecular weight 83.88 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Propa-1,2-dien-1-ylboronic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 83.88 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.
