2-(Difluoromethyl)-4-iodo-3-nitropyridine-5-acetic acid CAS 1805262-34-3

Description

The occurrence of 2-(Difluoromethyl)-4-iodo-3-nitropyridine-5-acetic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(Difluoromethyl)-4-iodo-3-nitropyridine-5-acetic acid (CAS 1805262-34-3), molecular formula C8H5F2IN2O4 and molecular weight 358.04 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H5F2IN2O4, 2-(Difluoromethyl)-4-iodo-3-nitropyridine-5-acetic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 358.04 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
