Description

3-(3,5-Di-tert-Butyl-4-Hydroxyphenyl)Propanohydrazide is a specialized phenolic hydrazide derivative that functions as a highly effective antioxidant and metal deactivator. This compound is critical for preventing oxidative degradation and extending the service life of polymers and other sensitive materials. It is primarily sought by formulators and manufacturers in the plastics, rubber, and specialty chemical industries who require robust stabilization solutions for their products.

Application

• Primary antioxidant and metal deactivator in polyolefins (e.g., polyethylene, polypropylene).
• Stabilizer component in synthetic rubbers and elastomers to prevent thermal-oxidative aging.
• Additive in lubricants, greases, and fuels to inhibit oxidation and sludge formation.
• Intermediate for the synthesis of more complex hindered phenol antioxidants.
• Stabilizing agent in adhesives and sealants to enhance shelf-life and performance.
• Protective additive in wire and cable insulation compounds.

Quality Control

Our production of 3-(3,5-Di-tert-Butyl-4-Hydroxyphenyl)Propanohydrazide adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; it is recommended to store under an inert atmosphere such as nitrogen for long-term preservation and to minimize exposure to air after opening the original container.
