Description

2-(tert-Butyl)-3,3-Dimethyl-1-Butene is a highly branched, terminal alkene characterized by its sterically hindered structure. This unique molecular architecture makes it a valuable intermediate in organic synthesis, particularly for introducing bulky tert-butyl groups and for applications requiring specific steric and electronic properties. It is primarily utilized by research chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for the synthesis of complex molecules, ligands, and advanced materials.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs), especially those requiring sterically hindered alkene functionalities or tert-butyl substituents.
• Agrochemical Synthesis: Used in the production of advanced pesticides, herbicides, and plant growth regulators where its bulky structure can influence biological activity and stability.
• Specialty Polymer & Material Science: Acts as a monomer or co-monomer for creating polymers with specific thermal and mechanical properties, or as a precursor for functionalized materials.
• Organic Synthesis & Catalysis: Employed as a reagent in Diels-Alder reactions, hydrofunctionalizations, and other transformations where its electron-rich double bond and steric bulk are advantageous.
• Ligand & Catalyst Development: Utilized to synthesize novel phosphine, N-heterocyclic carbene (NHC), and other ligands for transition metal catalysis.
• Flavor & Fragrance Industry: Potential intermediate for the synthesis of certain terpenoid-derived aroma chemicals.

Quality Control

Our 2-(tert-Butyl)-3,3-Dimethyl-1-Butene is produced and handled under a strict quality management system. Every batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee it meets your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Recommended storage temperature is 2-8°C for long-term stability. The container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent potential oxidation or moisture uptake.
