Chemical Structure
Description
The occurrence of 4-iodobenzoyl chloride is closely related to a hydroxyl group, an ether linkage, chlorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-iodobenzoyl chloride (CAS 1711-02-0), molecular formula C7H10ClIO and molecular weight 272.51 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, chlorine/iodine substitution, 4-iodobenzoyl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 272.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
