Chemical Structure
Description
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.
CATO supplies n-(3-Ethylphenyl)-6-methyl-1,1-dioxo-3,4-dihydro-2h-1lambda6,2,4-benzothiadiazine-3-carboxamide (CAS 1357633-30-7), a certified reference material (molecular formula C17H19N3O3S, MW 345.42 g/mol) for analytical method development and quality control.
Structurally, n-(3-Ethylphenyl)-6-methyl-1,1-dioxo-3,4-dihydro-2h-1lambda6,2,4-benzothiadiazine-3-carboxamide (C17H19N3O3S) 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 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 345.42 g/mol, it falls into the moderately-high-molecular-weight range. 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.
