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 4-Ethoxy-3-(3-(pyridin-4-yl)ureido)benzene-1-sulfonyl chloride sulfate (CAS 820245-44-1), a certified reference material (molecular formula C14H15ClN3O4SHO4S, MW 453.87 g/mol) for analytical method development and quality control.
4-Ethoxy-3-(3-(pyridin-4-yl)ureido)benzene-1-sulfonyl chloride sulfate (C14H15ClN3O4SHO4S) 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, 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).
As a certified reference material (CRM), 4-Ethoxy-3-(3-(pyridin-4-yl)ureido)benzene-1-sulfonyl chloride sulfate 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.
