Chemical Structure
Description
The occurrence of (4-((trimethylsilyl)ethynyl)phenyl)boronic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4-((trimethylsilyl)ethynyl)phenyl)boronic acid (CAS 630127-51-4), molecular formula C11H21BO2Si and molecular weight 224.18 g/mol, is a CATO reference standard with documented purity and traceability.
(4-((trimethylsilyl)ethynyl)phenyl)boronic acid (C11H21BO2Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 (4-((trimethylsilyl)ethynyl)phenyl)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.
