Description
Compared with other compounds in its class, the molecular weight of 267.39 g/mol gives 5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalene-2-sulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalene-2-sulfonamide (CAS 1235965-41-9), molecular formula C14H21NO2S and molecular weight 267.39 g/mol, is a CATO reference standard with documented purity and traceability.
5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalene-2-sulfonamide (C14H21NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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 5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalene-2-sulfonamide 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.
