Chemical Structure

3-bromo-5-iodo-1-methyl-pyridin-2-one CAS 1433855-64-1 chemical structure

Description

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.

3-bromo-5-iodo-1-methyl-pyridin-2-one (CAS 1433855-64-1), molecular formula C6H9BrINO and molecular weight 317.95 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-bromo-5-iodo-1-methyl-pyridin-2-one (C6H9BrINO) contains an amide group, a hydroxyl group, an ether linkage, bromine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 317.95 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
