Description

73463-39-5 CAPSO MFCD00041778 3-(cyclohexylamino)-1-hydroxypropane-1-sulfonic acid 3-(Cyclohexylamino)-2-hydroxy-1-propanesulfonic acid (CAS 73463-39-5) is a high-purity analytical reference standard with the molecular formula C9H19NO4S and a molecular weight of 237.32 g/mol.

73463-39-5 CAPSO MFCD00041778 3-(cyclohexylamino)-1-hydroxypropane-1-sulfonic acid 3-(Cyclohexylamino)-2-hydroxy-1-propanesulfonic acid (C9H19NO4S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
