Description

Decylmagnesium Chloride CAS NO 20157-33-9 is a versatile organomagnesium halide (Grignard reagent) widely used as a key building block in organic synthesis. Its primary value lies in its ability to act as a strong nucleophile and base, facilitating the formation of carbon-carbon bonds to introduce decyl groups into target molecules. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require precise alkyl chain elongation and functional group transformations.

Application

• Pharmaceutical Intermediates: Synthesis of active pharmaceutical ingredients (APIs) requiring long alkyl chains for lipophilicity or specific biological activity.
• Agrochemical Synthesis: Production of herbicides, fungicides, and plant growth regulators where the decyl moiety enhances efficacy and environmental persistence.
• Specialty Polymer & Material Science: Used as an initiator or modifier in the production of polymers, surfactants, and liquid crystals to tailor physical properties.
• Fine Chemical Manufacturing: Key reagent for the preparation of alcohols, carboxylic acids, and ketones via reactions with carbonyl compounds like aldehydes, ketones, and carbon dioxide.
• Catalyst & Ligand Preparation: Serves as a precursor for organometallic catalysts and complex ligands used in asymmetric synthesis and cross-coupling reactions.
• Flavor & Fragrance Industry: Synthesis of aroma chemicals and fragrance components that incorporate decyl groups for specific scent profiles.

Quality Control

Our Decylmagnesium Chloride is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including titration for active Grignard concentration and GC analysis for solvent and impurity profiles, to ensure consistency and high reactivity. Certificates of Analysis (COA) detailing purity, concentration, and physical properties are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and moisture-sensitive nature, this material must be stored under a dry, inert atmosphere (argon or nitrogen) at temperatures between 2°C and 8°C. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, oxidizers, and protic solvents. Use appropriate ventilation and grounding procedures in storage areas.
