Chemical Structure
Description
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.
CATO supplies Tetramethylammonium Dichloroiodate (CAS 1838-41-1), a certified reference material (molecular formula Cl2IC4H12N, MW 271.95 g/mol) for analytical method development and quality control.
Owing to chlorine/iodine substitution, Tetramethylammonium Dichloroiodate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.95 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.
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.
