Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(2,3-Dimethoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 488850-92-6), molecular formula C14H21BO4 and molecular weight 264.13 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H21BO4, 2-(2,3-Dimethoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 264.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
