Chemical Structure

Diiodochloromethane CAS 638-73-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diiodochloromethane.

CATO supplies Diiodochloromethane (CAS 638-73-3), a certified reference material (molecular formula CHClI2, MW 302.28 g/mol) for analytical method development and quality control.

Based on its molecular formula CHClI2, Diiodochloromethane contains chlorine/iodine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 302.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
