Chemical Structure
Description
n-[4-(2-amino-1,3-thiazol-4-yl)phenyl]-N-methylmethanesulfonamide (C11H13N3O2S2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
n-[4-(2-amino-1,3-thiazol-4-yl)phenyl]-N-methylmethanesulfonamide (CAS 852388-68-2), molecular formula C11H13N3O2S2 and molecular weight 283.37 g/mol, is a CATO reference standard with documented purity and traceability.
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.
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.
