Description

Palmitic Anhydride is a high-purity, long-chain fatty acid anhydride derived from palmitic acid. This versatile chemical intermediate is crucial for introducing the palmitoyl moiety into target molecules, enabling precise synthesis and modification. It is essential for manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking reliable, high-quality raw materials for advanced production processes.

Application

• Pharmaceutical Synthesis: A key reagent for the acylation of active pharmaceutical ingredients (APIs) and the production of prodrugs.
• Agrochemical Manufacturing: Used in the synthesis of specific pesticides, herbicides, and plant growth regulators requiring fatty acid derivatives.
• Polymer & Resin Production: Acts as a monomer or modifier in the creation of specialty polyesters, alkyd resins, and plasticizers.
• Lubricant & Grease Additives: Serves as a precursor for manufacturing high-performance esters used in synthetic lubricants and industrial greases.
• Cosmetic & Personal Care Ingredients: Employed in the synthesis of emollients, surfactants, and other conditioning agents.
• Organic Synthesis & Research: A valuable building block in academic and industrial R&D for creating novel organic compounds.

Quality Control

Our Palmitic Anhydride is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for demanding industrial applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation. Recommended storage temperature is 2-8°C for long-term stability.
