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-(7-methylnaphthalen-1-yl)-1,3,2-dioxaborolane (CAS 2304635-11-6), molecular formula C17H21BO2 and molecular weight 268.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,4,5,5-Tetramethyl-2-(7-methylnaphthalen-1-yl)-1,3,2-dioxaborolane (C17H21BO2) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
