Chemical Structure

2,5-Bis(triethoxysilyl)thiophene CAS 40190-22-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,5-Bis(triethoxysilyl)thiophene.

2,5-Bis(triethoxysilyl)thiophene (CAS 40190-22-5) is a high-purity analytical reference standard with the molecular formula C16H32O6SSi2 and a molecular weight of 408.66 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 2,5-Bis(triethoxysilyl)thiophene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
