Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies N-(2-Nitrophenylsulfenyl)-L-tyrosine (dicyclohexylammonium) salt (CAS 7675-56-1), a certified reference material (molecular formula C15H13N2O5SC12H24N, MW 515.67 g/mol) for analytical method development and quality control.
N-(2-Nitrophenylsulfenyl)-L-tyrosine (dicyclohexylammonium) salt (C15H13N2O5SC12H24N) contains a steroid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
