Chemical Structure

1,4,10,13-Tetrathia-7,16-diazacyclooctadecane CAS 20934-69-4 chemical structure

Description

CATO supplies 1,4,10,13-Tetrathia-7,16-diazacyclooctadecane (CAS 20934-69-4), a certified reference material (molecular formula C12H26N2S4, MW 326.61 g/mol) for analytical method development and quality control.

The molecular framework of 1,4,10,13-Tetrathia-7,16-diazacyclooctadecane (C12H26N2S4) is characterized by sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
