CATO supplies 2-[(4-Nitro-2,1,3-benzoxadiazol-5-yl)sulfanyl]acetic acid (CAS 799256-28-3), a certified reference material (molecular formula C8H5N3O5S, MW 255.21 g/mol) for analytical method development and quality control.
2-[(4-Nitro-2,1,3-benzoxadiazol-5-yl)sulfanyl]acetic acid (C8H5N3O5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
