Description

Isopalmitic Chloride is a versatile organic acid chloride derivative, specifically the acyl chloride of isopalmitic acid. This compound serves as a crucial high-purity building block for introducing the branched-chain isopalmitoyl moiety into target molecules, enabling the synthesis of specialized esters, amides, and polymers. It is essential for R&D and production in industries such as pharmaceuticals, agrochemicals, and specialty polymer manufacturing, where its unique branched structure imparts specific physical and performance properties.

Application

• Pharmaceutical Intermediates: Key reagent for synthesizing active pharmaceutical ingredients (APIs) and prodrugs requiring the isopalmitoyl group.
• Agrochemical Synthesis: Used in the production of specialized herbicides, fungicides, and plant growth regulators.
• Polymer & Resin Modification: Acts as a monomer or modifier in the synthesis of polyamides, polyesters, and coatings to enhance flexibility, hydrophobicity, and thermal stability.
• Lubricant & Fuel Additives: Employed in creating high-performance esters that improve lubricity, viscosity index, and low-temperature properties.
• Surfactant & Emulsifier Production: Serves as a precursor for synthesizing specialty surfactants with unique branching for improved solubility and surface activity.
• Cosmetic & Personal Care Ingredients: Used to manufacture emollients, wax esters, and other conditioning agents for skin and hair care formulations.
• Organic Synthesis & Research: A valuable reagent in academic and industrial laboratories for acylation reactions and the development of novel chemical entities.

Quality Control

Our Isopalmitic Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for demanding synthetic applications. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting key parameters such as assay, identity, and impurity profiles. Specifications can be tailored to meet specific customer requirements, including those for pharmaceutical and agrochemical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive) and reacts vigorously with water, alcohols, and strong bases. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture absorption. Isolate from incompatible materials such as strong oxidizers, bases, and moisture.
