Chemical Structure
Description
As a certified reference material (CRM), 3-[[(1,1-Dimethylethyl)dimethylsilyl]oxy]-butanoic Acid Ethyl 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.
3-[[(1,1-Dimethylethyl)dimethylsilyl]oxy]-butanoic Acid Ethyl Ester (CAS 81327-43-7) is a high-purity analytical reference standard with the molecular formula C12H26O3Si and a molecular weight of 246.42 g/mol.
3-[[(1,1-Dimethylethyl)dimethylsilyl]oxy]-butanoic Acid Ethyl Ester (C12H26O3Si) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
