Description

Isobutylene Oxide CAS NO 558-30-5 is a versatile and highly reactive epoxide compound, serving as a crucial building block in organic synthesis. Its value lies in its strained three-membered oxirane ring, which readily undergoes ring-opening reactions with various nucleophiles, enabling the creation of valuable intermediates. This chemical is essential for manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to develop new products or optimize synthesis routes.

Application

• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Agrochemical Synthesis: Serves as a key precursor for manufacturing herbicides, fungicides, and plant growth regulators.
• Polymer & Resin Modification: Employed as a cross-linking agent or monomer to modify the properties of specialty polymers, coatings, and adhesives.
• Chemical Derivatization: Acts as an alkylating agent to introduce the isobutyl group into target molecules.
• Surface Active Agents: Used in the production of specialty surfactants and emulsifiers.
• Fuel & Lubricant Additives: A component in the synthesis of performance-enhancing additives.

Quality Control

Our Isobutylene Oxide is manufactured under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including GC analysis for purity and identity verification, to ensure it meets exacting specifications for industrial and research applications. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile nature, containers must be kept tightly sealed when not in use to prevent evaporation and concentration of vapors. Keep away from incompatible materials such as strong acids, bases, and oxidizing agents.
