Compared with other compounds in its class, the molecular weight of 200.27 g/mol gives tert-Butyl 3-oxoheptanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
tert-Butyl 3-oxoheptanoate (CAS 66696-98-8), molecular formula C11H20O3 and molecular weight 200.27 g/mol, is a CATO reference standard with documented purity and traceability.
tert-Butyl 3-oxoheptanoate (C11H20O3) 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.
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 tert-Butyl 3-oxoheptanoate 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.
