Description

Ethyl Iodooctadecanoate is a high-purity, long-chain alkyl iodide ester, also known as ethyl iodostearate. This specialty organic intermediate is valued for its reactivity, particularly in introducing iodine-containing functional groups into target molecules. It serves as a critical building block for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, where precise chemical modification is required.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring iodine atoms for bioactivity or as radiolabeling precursors.
• Agrochemical Synthesis: Serves as a key reagent in the production of specialized pesticides, herbicides, and plant growth regulators.
• Liquid Crystal & OLED Material Precursor: Acts as a starting material for synthesizing iodine-functionalized organic molecules used in electronic displays and optoelectronic devices.
• Polymer Modification: Employed to introduce iodine-containing side chains into polymers, altering properties like refractive index, stability, or enabling further chemical grafting.
• Organic Synthesis & Research: A versatile reagent for coupling reactions (e.g., Heck-type reactions) and nucleophilic substitution in complex molecule construction within R&D laboratories.
• Surfactant & Specialty Chemical Production: Used in the manufacture of iodinated surfactants and other specialty chemicals with specific surface-active or antimicrobial properties.

Quality Control

Our Ethyl Iodooctadecanoate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for advanced synthetic applications. A Certificate of Analysis (COA) detailing specific results for purity, identity, and related substances is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be amber glass or opaque.
