Chemical Structure

Methyl 5-bromo-3-cyano-6-isobutyl-2-oxo-1,2-dihydropyridine-4-carboxylate CAS 1674390-02-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 313.15 g/mol gives Methyl 5-bromo-3-cyano-6-isobutyl-2-oxo-1,2-dihydropyridine-4-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 5-bromo-3-cyano-6-isobutyl-2-oxo-1,2-dihydropyridine-4-carboxylate (CAS 1674390-02-3), molecular formula C12H13BrN2O3 and molecular weight 313.15 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl 5-bromo-3-cyano-6-isobutyl-2-oxo-1,2-dihydropyridine-4-carboxylate (C12H13BrN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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.
