Description

The occurrence of 2,2'-Bithiophene-5-boronic Acid Pinacol Ester 2-(2,2'-Bithiophen-5-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 479719-88-5 5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2,2'-bithiophene T2518 is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,2'-Bithiophene-5-boronic Acid Pinacol Ester 2-(2,2'-Bithiophen-5-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 479719-88-5 5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2,2'-bithiophene T2518 (CAS 479719-88-5) is a high-purity analytical reference standard with the molecular formula C14H25BO2S2 and a molecular weight of 300.29 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 2,2'-Bithiophene-5-boronic Acid Pinacol Ester 2-(2,2'-Bithiophen-5-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 479719-88-5 5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2,2'-bithiophene T2518 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.29 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), 2,2'-Bithiophene-5-boronic Acid Pinacol Ester 2-(2,2'-Bithiophen-5-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 479719-88-5 5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2,2'-bithiophene T2518 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.
