Chemical Structure
Description
Structurally, Methyl 4-(2-((4-ethyl-5-(pyrazin-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamido)benzoate (C18H18N6O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 398.44 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies Methyl 4-(2-((4-ethyl-5-(pyrazin-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetamido)benzoate (CAS 585554-55-8), a certified reference material (molecular formula C18H18N6O3S, MW 398.44 g/mol) for analytical method development and quality control.
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.
