Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 294.09 g/mol gives 3-Iodo-5-methyl-pyridin-2-ylamine acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Iodo-5-methyl-pyridin-2-ylamine acetate (CAS 1820620-00-5) is a high-purity analytical reference standard with the molecular formula C6H7IN2C2H4O2 and a molecular weight of 294.09 g/mol.
3-Iodo-5-methyl-pyridin-2-ylamine acetate (C6H7IN2C2H4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
