Chemical Structure

Guazatine Sesquisulfate Salt CAS 26643-62-9 chemical structure

Description

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.

CATO supplies Guazatine Sesquisulfate Salt (CAS 26643-62-9), a certified reference material (molecular formula C18H44N7O4S, MW 454.65 g/mol) for analytical method development and quality control.

Structurally, Guazatine Sesquisulfate Salt (C18H44N7O4S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 454.65 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.
