Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, 3-[2-(Tetrahydro-2H-pyran-2-ylethoxy)phenoxy]-4,4,5,5-tetramethyl-[1,3,2]dioxaboralane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 3-[2-(Tetrahydro-2H-pyran-2-ylethoxy)phenoxy]-4,4,5,5-tetramethyl-[1,3,2]dioxaboralane (CAS 1334165-03-5), a certified reference material (molecular formula C19H29BO5, MW 348.24 g/mol) for analytical method development and quality control.
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.
