Chemical Structure

1,8-Diiodoanthracene CAS 189105-78-0 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 1,8-Diiodoanthracene (CAS 189105-78-0), a certified reference material (molecular formula C14H8I2, MW 430.02 g/mol) for analytical method development and quality control.

Owing to iodine substitution, a polycyclic aromatic system, 1,8-Diiodoanthracene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 430.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
