Chemical Structure
Description
5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalene-2-sulfonyl chloride (C14H19ClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalene-2-sulfonyl chloride (CAS 132392-26-8) is a high-purity analytical reference standard with the molecular formula C14H19ClO2S and a molecular weight of 286.82 g/mol.
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.
