2-((5-(2-Ethoxyphenyl)-1,3,4-thiadiazol-2-yl)amino)cyclohex-1-ene-1-carboxylic acid (CAS 160893-98-1), molecular formula C17H19N3O3S and molecular weight 345.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((5-(2-Ethoxyphenyl)-1,3,4-thiadiazol-2-yl)amino)cyclohex-1-ene-1-carboxylic acid (C17H19N3O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
