For chemical engineers, R&D scientists, and procurement specialists, a thorough understanding of a compound's chemical properties is fundamental to its effective application and successful sourcing. Sebacoyl Chloride, known by its CAS number 111-19-3, is a highly reactive bifunctional acyl chloride with specific characteristics that make it invaluable in various industrial processes, particularly in polymer synthesis and the creation of specialty chemicals. As a prominent manufacturer and supplier, we aim to provide clarity on these vital properties.

The molecular formula for Sebacoyl Chloride is C10H16Cl2O2, with a molecular weight of 239.14. Its most defining characteristic is the presence of two acid chloride (-COCl) functional groups at opposite ends of a ten-carbon aliphatic chain. This structure imparts significant reactivity. Acid chlorides are highly susceptible to nucleophilic attack, readily reacting with alcohols, amines, and water. This reactivity is precisely why it is a sought-after intermediate. When R&D professionals decide to buy Sebacoyl Chloride, they are harnessing this reactivity for precise chemical synthesis.

Key physical properties provided by manufacturers are also critical for handling and processing. Sebacoyl Chloride typically appears as a yellow liquid. Its boiling point is reported around 166-168 °C at 12 mmHg, indicating it is a relatively high-boiling liquid that can be handled under standard atmospheric conditions, though vacuum distillation might be employed for purification. The density is approximately 1.121 g/mL at 25 °C, which is slightly denser than water. Its refractive index, often around 1.468 (n20/D), is a standard parameter for quality control and identification.

The melting point of Sebacoyl Chloride is typically in the range of -5 to -2 °C, meaning it remains a liquid at standard room temperatures, simplifying its transfer and use in manufacturing processes. While miscible with hydrocarbons and ethers, it reacts vigorously with water, releasing hydrochloric acid (HCl) and sebacic acid. Therefore, proper storage and handling precautions are essential. When you purchase Sebacoyl Chloride, ensure it is stored in tightly sealed containers in a cool, dry place, away from moisture and incompatible substances.

The high purity of Sebacoyl Chloride, often specified as ≥92% or ≥95% via titration or GC analysis, is crucial for achieving predictable reaction outcomes. Impurities can lead to side reactions, reduced yields, and compromised properties in the final products, such as polyamides or polyesters. For procurement managers and chemical formulators, selecting a supplier that guarantees consistent purity and provides comprehensive technical data is paramount. We, as a dedicated manufacturer in China, ensure our Sebacoyl Chloride meets these demanding specifications.
