1,2-dibutyl squarate 2892-62-8 3,4-Dibutoxy-3-cyclobutene-1,2-dione 3,4-di-n-butoxy-3-cyclobutene-1,2-dione 3,4-dibutoxycyclobut-3-ene-1,2-dione CHEBI:53612 SADBE squaric acid dibutyl ester squaric acid dibutylester (CAS 2892-62-8), molecular formula C12H18O4 and molecular weight 226.27 g/mol, is a CATO reference standard with documented purity and traceability.

1,2-dibutyl squarate 2892-62-8 3,4-Dibutoxy-3-cyclobutene-1,2-dione 3,4-di-n-butoxy-3-cyclobutene-1,2-dione 3,4-dibutoxycyclobut-3-ene-1,2-dione CHEBI:53612 SADBE squaric acid dibutyl ester squaric acid dibutylester (C12H18O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
