4,4,5,5-Tetramethyl-2-(phenoxathiin-4-yl)-1,3,2-dioxaborolane CAS 2290561-93-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4,5,5-Tetramethyl-2-(phenoxathiin-4-yl)-1,3,2-dioxaborolane.

4,4,5,5-Tetramethyl-2-(phenoxathiin-4-yl)-1,3,2-dioxaborolane (CAS 2290561-93-0) is a high-purity analytical reference standard with the molecular formula C18H19BO3S and a molecular weight of 326.22 g/mol.

Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, 4,4,5,5-Tetramethyl-2-(phenoxathiin-4-yl)-1,3,2-dioxaborolane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 4,4,5,5-Tetramethyl-2-(phenoxathiin-4-yl)-1,3,2-dioxaborolane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
