Description

Octadecylmagnesium Chloride is a long-chain alkyl Grignard reagent, a highly versatile organometallic compound essential for introducing the octadecyl (stearyl) group into target molecules. Its primary value lies in enabling precise carbon-carbon bond formation, a critical step in synthesizing specialty chemicals, advanced materials, and pharmaceutical intermediates. This reagent is particularly sought after by R&D laboratories and production facilities in the pharmaceutical, agrochemical, and advanced polymer industries for creating surfactants, lubricant additives, and other high-value functionalized compounds.

Application

• Pharmaceutical Intermediate Synthesis: Used as a key reagent for the alkylation of active pharmaceutical ingredients (APIs) and fine chemicals.
• Agrochemical Production: Employed in the synthesis of long-chain alkylated pesticides, herbicides, and plant growth regulators.
• Polymer & Material Science: Serves as an initiator or modifier in the production of specialized polymers, surfactants, and surface-coating agents.
• Lubricant & Fuel Additive Synthesis: Integral for creating high-performance viscosity modifiers and anti-wear additives.
• Organic Synthesis & Research: A fundamental tool in academic and industrial R&D for constructing complex organic molecules via Grignard reactions.
• Surface Modification: Used to graft hydrophobic octadecyl chains onto various material surfaces to alter wettability and functionality.

Quality Control

Our Octadecylmagnesium Chloride is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including titration for active Grignard concentration and spectroscopic analysis for purity and identity. We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring traceability and compliance with your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. This product is easily oxidized (store under inert atmosphere) and reacts with strong acid/organic solvent. For optimal stability, store under a dry, inert atmosphere (argon or nitrogen) at 2-8°C. The solution is typically supplied in septum-sealed bottles or Sure/Seal™ containers. Keep away from heat, sparks, open flames, and incompatible materials such as water, alcohols, and acids.
