Chemical Structure
Description
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 5-Amino-2-ethoxybenzene-1-sulfonamide hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 252.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
5-Amino-2-ethoxybenzene-1-sulfonamide hydrochloride (CAS 1171768-81-2) is a high-purity analytical reference standard with the molecular formula C8H12N2O3SHCl and a molecular weight of 252.71 g/mol.
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.
