Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies dimethyl [(tetramethyl-1,3,2-dioxaborolan-2-yl)methyl]phosphonate (CAS 228716-55-0), a certified reference material (molecular formula C9H20BO5P, MW 250.04 g/mol) for analytical method development and quality control.
The molecular framework of dimethyl [(tetramethyl-1,3,2-dioxaborolan-2-yl)methyl]phosphonate (C9H20BO5P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
