Product Introduction
1-Bromo-2-methylpropane (CAS 78-77-3), widely known as Isobutyl bromide, is an organic compound with the molecular formula C4H9Br. It appears as a colorless to pale yellow liquid with a characteristic sweet, ethereal odor. As a primary alkyl bromide, 1-Bromo-2-methylpropane (CAS 78-77-3) is a versatile and highly reactive building block in organic chemistry. It serves as an essential alkylating agent, allowing for the efficient introduction of the isobutyl moiety into a wide variety of chemical structures, including amines, phenols, and carbon nucleophiles.
Product Selling Points
-
High Alkylating Efficiency: Its primary bromide structure makes it an excellent substrate for Nucleophilic Substitution (SN2) reactions.
-
Superior Purity (≥ 99.0%): Chemfine ensures a strictly controlled distillation process to minimize secondary isomers and residual isobutanol.
-
Low Moisture Content (≤ 0.05%): Minimized water content prevents hydrolysis and ensures high yields in moisture-sensitive Grignard and organometallic reactions.
-
Optimal Reactivity: Provides a balanced reaction rate compared to isobutyl chloride or isobutyl iodide, making it the preferred choice for industrial scale-up.
-
Strict Isomer Control: Guaranteed low levels of tert-butyl bromide and n-butyl bromide to ensure downstream product consistency.
-
Global Logistics Compliance: Shipped in UN-approved packaging with complete documentation for hazardous material transport (Class 3, Flammable).
Applications
Pharmaceutical Synthesis A critical intermediate for the synthesis of various active pharmaceutical ingredients (APIs), particularly those requiring an isobutyl group, such as certain anti-inflammatory agents and analgesics.
Flavor and Fragrance Industry Used to synthesize isobutyl esters and ethers which are valuable components in the formulation of fruit-flavored essences and floral fragrances.
Organic Synthesis and Research Acts as a standard reagent for the formation of Grignard reagents (Isobutylmagnesium bromide) and as a precursor for various isobutyl-substituted organic compounds.
Pesticides and Agrochemicals Utilized as a building block in the development of modern herbicides and fungicides where the branched alkyl chain influences biological activity and lipophilicity.
Polymer Modifiers Employed in the synthesis of specialized monomers or as a chain transfer agent in certain radical polymerization processes to modify the physical properties of resins.
Packaging

Storage
1-Bromo-2-methylpropane is a flammable and light-sensitive liquid. It must be stored in a cool, dry, and well-ventilated warehouse away from direct sunlight and heat sources. Keep containers tightly sealed to prevent evaporation and moisture absorption. Store in a dedicated flammable liquids area, away from strong bases, strong oxidizing agents, and aluminum/magnesium powder. Properly stored, it has a shelf life of 12-18 months.
