Chemical Structure

23-(9-Mercaptononyl)-3,6,9,12,15,18,21-heptaoxatricosanoic Acid CAS 221222-49-7 chemical structure

Description

23-(9-Mercaptononyl)-3,6,9,12,15,18,21-heptaoxatricosanoic Acid (CAS 221222-49-7), molecular formula C25H50O9S and molecular weight 526.72 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 23-(9-Mercaptononyl)-3,6,9,12,15,18,21-heptaoxatricosanoic Acid (C25H50O9S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
