Description
CATO supplies 4,4,5,5-Tetramethyl-2-(2-oxaspiro[4.5]dec-7-en-8-yl)-1,3,2-dioxaborolane (CAS 1825371-79-6), a certified reference material (molecular formula C15H25BO3, MW 264.17 g/mol) for analytical method development and quality control.
Structurally, 4,4,5,5-Tetramethyl-2-(2-oxaspiro[4.5]dec-7-en-8-yl)-1,3,2-dioxaborolane (C15H25BO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 264.17 g/mol, it falls into the medium-molecular-weight range. 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).
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.
