(2S,4E,6R,8S)-8-[[(1,1-Dimethylethyl)dimethylsilyl]oxy]-2,4,6-trimethyl-4-nonenoic Acid Ethyl Ester (CAS 119433-08-8) is a high-purity analytical reference standard with the molecular formula C20H40O3Si and a molecular weight of 356.62 g/mol.
(2S,4E,6R,8S)-8-[[(1,1-Dimethylethyl)dimethylsilyl]oxy]-2,4,6-trimethyl-4-nonenoic Acid Ethyl Ester (C20H40O3Si) 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.
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.
CATO manufactures (2S,4E,6R,8S)-8-[[(1,1-Dimethylethyl)dimethylsilyl]oxy]-2,4,6-trimethyl-4-nonenoic Acid Ethyl Ester 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.
