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 5-(t-Butyldimethylsilyloxymethyl)thiophen-3-boronic acid.
CATO supplies 5-(t-Butyldimethylsilyloxymethyl)thiophen-3-boronic acid (CAS 2122282-85-1), a certified reference material (molecular formula C11H21BO3SSi, MW 272.24 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 5-(t-Butyldimethylsilyloxymethyl)thiophen-3-boronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 272.24 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.
CATO manufactures 5-(t-Butyldimethylsilyloxymethyl)thiophen-3-boronic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
