CAS 21901-34-8: 3-Methyl-5-nitro-2(1H)-pyridinone

Description: 3-Methyl-5-nitro-2(1H)-pyridinone, with the CAS number 21901-34-8, is a heterocyclic organic compound characterized by a pyridine ring substituted with a methyl group and a nitro group. This compound typically exhibits a pale yellow to light brown appearance and is soluble in polar solvents such as water and alcohols, owing to the presence of the nitro group, which enhances its polarity. The presence of the methyl group contributes to its hydrophobic characteristics, while the nitro group can participate in various chemical reactions, including nucleophilic substitutions and reductions. 3-Methyl-5-nitro-2(1H)-pyridinone is of interest in pharmaceutical and agrochemical research due to its potential biological activity, including antimicrobial and anti-inflammatory properties. Its reactivity and functional groups make it a valuable intermediate in organic synthesis. As with many nitro compounds, it should be handled with care due to potential toxicity and environmental concerns. Proper safety measures should be observed when working with this substance in laboratory settings.
