Chemical Structure
Description
Dimethyl (3-methylbuta-1,2-dien-1-yl)boronate (CAS 61357-30-0), molecular formula C7H13BO2 and molecular weight 139.99 g/mol, is a CATO reference standard with documented purity and traceability.
Dimethyl (3-methylbuta-1,2-dien-1-yl)boronate (C7H13BO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
