Description

4-Isopropylphenol (CAS NO 99-89-8) is a versatile alkylphenol derivative widely used as a key synthetic intermediate in the chemical industry. Its phenolic structure and isopropyl substituent make it a valuable building block for the production of antioxidants, polymer additives, and specialty chemicals. This compound is essential for manufacturers in the agrochemical, pharmaceutical, and polymer sectors seeking reliable, high-purity raw materials for their synthesis processes.

Application

• Antioxidant Synthesis: A crucial precursor for manufacturing phenolic antioxidants like BHT (Butylated Hydroxytoluene) analogs, used to stabilize polymers, fuels, and lubricants against oxidative degradation.
• Agrochemical Intermediates: Serves as a key building block in the synthesis of certain herbicides, fungicides, and plant growth regulators.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals requiring alkylated phenol structures.
• Polymer Additives: Employed in the production of light stabilizers, plasticizers, and other functional additives for plastics and resins.
• Fragrance and Flavor Chemistry: Acts as an intermediate for creating specific aroma chemicals and flavoring agents.
• Surfactant and Resin Production: Utilized in the manufacture of alkylphenol-based surfactants, epoxy resins, and phenolic resins.

Quality Control

Our 4-Isopropylphenol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing key parameters such as assay, identity, and impurity profiles. Our quality commitment ensures the material meets the stringent requirements for use as a fine chemical intermediate.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its properties of being easily oxidized, it is recommended to store under an inert atmosphere for long-term storage. Keep container tightly sealed when not in use to minimize exposure to air and moisture.
