Description

Naphthalene, 1-Methyl-, Radical Ion(1-) (9Ci) CAS NO 34468-02-5 is a specialized organic anion radical derived from methylnaphthalene, serving as a critical reactive intermediate in advanced synthetic chemistry. Its unique electronic structure makes it invaluable for initiating and propagating complex polymerization reactions and facilitating challenging electron transfer processes. This high-purity intermediate is essential for R&D chemists and process engineers in the fine chemical, advanced material, and pharmaceutical sectors who require precise control over radical-mediated synthesis.

Application

• Polymerization Initiator: Acts as a key radical source for controlled radical polymerization (CRP) techniques, including ATRP and RAFT, to synthesize polymers with specific architectures.
• Organic Synthesis Intermediate: Employed in the synthesis of complex organic molecules, particularly where radical cyclization or functionalization steps are required.
• Electron Transfer Agent: Used in studies and applications involving redox chemistry and photoredox catalysis due to its well-defined radical anion character.
• Material Science Research: Serves as a building block or dopant in the development of conductive organic materials and charge-transfer complexes.
• Pharmaceutical Research: Utilized in exploratory routes for synthesizing novel active pharmaceutical ingredients (APIs) that involve radical intermediates.
• Catalysis Development: Functions as a model compound or co-catalyst in developing new catalytic systems for sustainable chemical transformations.

Quality Control

Our Naphthalene, 1-Methyl-, Radical Ion(1-) is manufactured under stringent conditions to ensure high reactivity and purity for research and process applications. Each batch is characterized using advanced analytical techniques, including NMR and EPR spectroscopy, to confirm identity and radical concentration. Certificates of Analysis (COA) detailing purity, assay, and solvent content are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and easily oxidized; it must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Handle and dispense in a controlled, oxygen-free environment to maintain integrity.
