Chemical Structure

2-FLuoro-5-iodo-4-methoxy-benzoic acid methyl ester CAS 1823590-32-4 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 2-FLuoro-5-iodo-4-methoxy-benzoic acid methyl ester.

CATO supplies 2-FLuoro-5-iodo-4-methoxy-benzoic acid methyl ester (CAS 1823590-32-4), a certified reference material (molecular formula C9H8FIO3, MW 310.06 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system, 2-FLuoro-5-iodo-4-methoxy-benzoic acid methyl ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 310.06 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.
