Chemical Structure
Description
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.
4,4,5,5-Tetramethyl-2-((1R,2S)-2-methylcyclopropyl)-1,3,2-dioxaborolane (CAS 1813575-99-3), molecular formula C10H19BO2 and molecular weight 182.07 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4,4,5,5-Tetramethyl-2-((1R,2S)-2-methylcyclopropyl)-1,3,2-dioxaborolane (C10H19BO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 182.07 g/mol, it falls into the medium-molecular-weight range. 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.
