(Z)-2-(But-2-en-2-yloxy)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 91890-01-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (Z)-2-(But-2-en-2-yloxy)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane.

(Z)-2-(But-2-en-2-yloxy)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 91890-01-6) is a high-purity analytical reference standard with the molecular formula C10H19BO3 and a molecular weight of 198.07 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (Z)-2-(But-2-en-2-yloxy)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 198.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
