Description

Stearic Acid Hydrazide is a high-purity organic compound derived from stearic acid, serving as a versatile chemical intermediate. Its bifunctional nature, featuring both a long alkyl chain and a reactive hydrazide group, makes it a critical building block for synthesizing specialized polymers, surfactants, and corrosion inhibitors. This product is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product performance and stability.

Application

• Polymer Additive & Modifier: Acts as a chain extender, cross-linking agent, or property modifier in polyurethane, nylon, and epoxy resin systems to improve mechanical strength and thermal stability.
• Corrosion Inhibitor Precursor: Used in the formulation of high-performance corrosion inhibitors for industrial lubricants, metalworking fluids, and fuel additives.
• Surfactant & Emulsifier Synthesis: Serves as a key intermediate for producing non-ionic surfactants and emulsifiers with specific hydrophobic-lipophilic balance (HLB) properties.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) and agrochemicals that require a long-chain hydrazide moiety.
• Chelating Agent: Functions as a ligand for metal ions in various catalytic and analytical chemistry applications.
• Textile & Leather Auxiliary Agent: Utilized in the production of softening agents, waterproofing agents, and other functional finishes.

Quality Control

Our Stearic Acid Hydrazide is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity, IR for identification, and loss on drying for moisture content, to ensure it meets exacting specifications. A detailed Certificate of Analysis (COA) is provided with each shipment, guaranteeing traceability and consistent batch-to-batch quality for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent oxidation and moisture absorption.
