Description

16-Methylheptadecanoic Acid Chloride is a specialized branched-chain fatty acid chloride derivative. This compound serves as a versatile and reactive intermediate for introducing the unique 16-methylheptadecanoyl moiety into target molecules. It is particularly valuable in the synthesis of fine chemicals, advanced polymers, and bioactive compounds where specific hydrophobic chain architecture is required. Researchers and industrial chemists in pharmaceuticals, agrochemicals, and material science utilize this acid chloride for its precise structural functionality.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs) and prodrugs requiring specific lipid-like properties.
• Agrochemical Synthesis: Used in the production of specialized surfactants, adjuvants, and active ingredients for crop protection formulations.
• Polymer & Material Science: Acts as a monomer or modifier in the creation of specialty polyesters, polyamides, and surface-coating agents to alter hydrophobicity and physical properties.
• Lubricant & Fuel Additive Precursor: Employed in synthesizing high-performance ester-based additives that improve lubricity and stability.
• Cosmetic & Personal Care Ingredients: Intermediate for producing emollients, wax esters, and other lipid components in skincare formulations.
• Bioconjugation & Probe Synthesis: Useful in biochemical research for labeling proteins or other biomolecules with long, branched hydrophobic tags.
• Organic Synthesis Reagent: A versatile acylating agent for nucleophiles such as amines and alcohols in complex multi-step synthetic routes.

Quality Control

Our 16-Methylheptadecanoic Acid Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing including HPLC for purity and IR & NMR for structural confirmation to ensure consistency and compliance with customer specifications. Comprehensive Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its moisture-sensitive and reactive nature. Keep away from strong bases, oxidizing agents, and sources of ignition.
