1-Chloro-5-fluoro-2-iodo-4-methylbenzene CAS 202982-69-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Chloro-5-fluoro-2-iodo-4-methylbenzene.

1-Chloro-5-fluoro-2-iodo-4-methylbenzene (CAS 202982-69-2) is a high-purity analytical reference standard with the molecular formula C7H5ClFI and a molecular weight of 270.47 g/mol.

The molecular framework of 1-Chloro-5-fluoro-2-iodo-4-methylbenzene (C7H5ClFI) is characterized by fluorine/chlorine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
