Chemical Structure

2-Iodo-4-methylbenzoyl chloride CAS 52107-97-8 chemical structure

Description

2-Iodo-4-methylbenzoyl chloride (CAS 52107-97-8) is a high-purity analytical reference standard with the molecular formula C8H6ClIO and a molecular weight of 280.49 g/mol.

2-Iodo-4-methylbenzoyl chloride (C8H6ClIO) contains a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
