CATO supplies 5-Formylamino-naphthalene-1-sulfonyl chloride 5-formylaminonaphthalene-1-sulfonyl chloride 680618-20-6 (CAS 680618-20-6), a certified reference material (molecular formula C11H8ClNO3S, MW 269.70 g/mol) for analytical method development and quality control.
5-Formylamino-naphthalene-1-sulfonyl chloride 5-formylaminonaphthalene-1-sulfonyl chloride 680618-20-6 (C11H8ClNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
