Chemical Structure

n-(6-Amino-1,3-benzothiazol-2-yl)ethane-1-sulfonamide CAS 954581-32-9 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-(6-Amino-1,3-benzothiazol-2-yl)ethane-1-sulfonamide.

n-(6-Amino-1,3-benzothiazol-2-yl)ethane-1-sulfonamide (CAS 954581-32-9) is a high-purity analytical reference standard with the molecular formula C9H11N3O2S2 and a molecular weight of 257.33 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, n-(6-Amino-1,3-benzothiazol-2-yl)ethane-1-sulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.33 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.

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.
