Chemical Structure

4-(tert-Butyl-dimethyl-silanyloxy)-but-2-ynoic acid methyl ester CAS 117968-51-1 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

4-(tert-Butyl-dimethyl-silanyloxy)-but-2-ynoic acid methyl ester (CAS 117968-51-1), molecular formula C11H20O3Si and molecular weight 228.36 g/mol, is a CATO reference standard with documented purity and traceability.

4-(tert-Butyl-dimethyl-silanyloxy)-but-2-ynoic acid methyl ester (C11H20O3Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.

As a certified reference material (CRM), 4-(tert-Butyl-dimethyl-silanyloxy)-but-2-ynoic acid methyl ester 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.
