5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thieno[2,3-b]pyridine CAS 1034579-02-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thieno[2,3-b]pyridine.

5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thieno[2,3-b]pyridine (CAS 1034579-02-6), molecular formula C13H24BNO2S and molecular weight 269.21 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thieno[2,3-b]pyridine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 269.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
