Description

Nysted Reagent CAS NO 41114-59-4 is a highly versatile organometallic reagent, specifically a methylenation reagent, widely recognized for its role in synthetic organic chemistry. Its primary value lies in its ability to efficiently convert carbonyl compounds into terminal alkenes, a critical transformation in the synthesis of complex molecules. This reagent is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials industries who require reliable and high-purity intermediates for building block synthesis.

Application

• Olefination Reactions: Key reagent for the methylenation of aldehydes and ketones to produce terminal alkenes (vinyl groups).
• Pharmaceutical Intermediates: Synthesis of key alkene-containing intermediates for active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Production of alkene-based building blocks for herbicides, fungicides, and insecticides.
• Fine Chemical Production: Used in the manufacture of flavors, fragrances, and specialty polymers.
• Material Science Research: Enabling the synthesis of novel organic ligands and monomers for advanced materials.
• Academic & R&D Laboratories: A staple tool for methodology development and complex natural product synthesis.

Quality Control

Our Nysted Reagent is manufactured under strict quality protocols to ensure batch-to-batch consistency and high reactivity. Each lot undergoes comprehensive analytical testing, including assay and purity verification by NMR and titration methods. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (argon or nitrogen) due to its moisture-sensitive and potentially pyrophoric nature. Keep away from heat, sparks, and open flames.
