Chemical Structure
Description
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 supplies 2-((4-Methoxyphenyl)amino)ethane-1-sulfonyl fluoride hydrochloride (CAS 129504-45-6), a certified reference material (molecular formula C9H12FNO3SHCl, MW 269.71 g/mol) for analytical method development and quality control.
2-((4-Methoxyphenyl)amino)ethane-1-sulfonyl fluoride hydrochloride (C9H12FNO3SHCl) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 2-((4-Methoxyphenyl)amino)ethane-1-sulfonyl fluoride hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
