Description

Pyridinium, 4-[(Hydroxyamino)Carbonyl]-1-Methyl-, Inner Salt is a specialized heterocyclic compound featuring a unique zwitterionic structure that combines a pyridinium cation with a hydroxamic acid-derived anion. This molecular architecture makes it a valuable intermediate and reagent in advanced synthetic chemistry, particularly for applications requiring specific metal chelation or as a precursor to functionalized pyridine derivatives. It is primarily sought by research institutions and industrial R&D departments focused on developing novel pharmaceuticals, agrochemicals, and specialty materials.

Application

• Key intermediate in the synthesis of novel pharmaceutical agents, particularly those targeting metalloenzymes.
• Precursor for the development of specialized ligands and catalysts in coordination chemistry.
• Building block for advanced agrochemical research, including the creation of new active ingredients.
• Reagent in organic synthesis for the introduction of hydroxamic acid functional groups.
• Component in material science research for creating functionalized surfaces or polymers.
• Starting material for the preparation of analytical standards and reference compounds.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We provide comprehensive analytical data to support your research and development needs. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request for every batch.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, the container should be purged with inert gas after each opening to maintain product integrity.
