Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including n-(2-(1h-Indol-3-yl)ethyl)-3,4-dimethoxybenzenesulfonamide.
CATO supplies n-(2-(1h-Indol-3-yl)ethyl)-3,4-dimethoxybenzenesulfonamide (CAS 880139-08-2), a certified reference material (molecular formula C18H20N2O4S, MW 360.43 g/mol) for analytical method development and quality control.
Structurally, n-(2-(1h-Indol-3-yl)ethyl)-3,4-dimethoxybenzenesulfonamide (C18H20N2O4S) contains a flavonoid 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 360.43 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.
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.
