In the intricate field of chemical synthesis, intermediates are the vital bridges connecting raw materials to complex, high-value compounds. 10-Chloro-1-Decanol, identified by its CAS number 51309-10-5, is a prominent example of such an intermediate, particularly valued for its utility in pharmaceutical synthesis and broader organic chemistry. This article delves into the synthesis, properties, and significant applications of 10-Chloro-1-Decanol, highlighting its importance for researchers and manufacturers, especially when sourced from reputable suppliers.

Understanding 10-Chloro-1-Decanol

10-Chloro-1-Decanol is a bifunctional organic molecule featuring a long, ten-carbon chain. At one end of this chain is a primary alcohol group (-OH), while at the other terminal carbon, a chlorine atom is attached. This dual functionality—a reactive hydroxyl group and a labile chlorine atom—renders it a highly versatile intermediate for various chemical transformations. Its molecular formula is C10H21ClO, with a molecular weight of approximately 192.73 g/mol. Physically, it typically presents as a pale yellow to yellow liquid, with a melting point in the range of 12-13°C and a boiling point of 126-128°C at 2 mmHg. For critical applications, especially in pharmaceuticals, ensuring a high assay purity, often ≥97.0%, is paramount.

Synthesis Pathways and Production

The synthesis of 10-Chloro-1-Decanol can be achieved through several established methods. Common routes include the reaction of 1-decanol with chlorinating agents like thionyl chloride (SOCl2), which selectively replaces the terminal hydroxyl group with a chlorine atom. Alternatively, strategies involving the functionalization of decanoic acid derivatives or the controlled addition of HCl to unsaturated long-chain alcohols can also yield the desired product. Industrial production often leverages optimized processes to ensure scalability, consistency, and cost-effectiveness. For companies seeking to purchase this compound, partnering with a dedicated 10-Chloro-1-Decanol manufacturer in China ensures access to efficiently produced, high-quality material.

Key Properties and Handling Considerations

Key physical and chemical properties that guide the use of 10-Chloro-1-Decanol include its density (around 0.951 g/mL) and refractive index (approximately 1.46). Its flash point of 121.9°C indicates a moderate flammability risk, necessitating appropriate safety precautions during handling and storage. As an irritant, safety measures such as wearing gloves and eye protection are recommended. Storage in a cool, ventilated place in a sealed container is crucial to maintain its stability and purity, especially for long-term inventory by a 10-Chloro-1-Decanol supplier.

Applications in Pharmaceutical Synthesis

The pharmaceutical industry extensively utilizes 10-Chloro-1-Decanol as a crucial intermediate. Its ability to readily undergo nucleophilic substitution reactions at the chlorine atom, or esterification/etherification at the hydroxyl group, makes it an ideal starting material for constructing complex molecular architectures. It can be used to:

  • Introduce specific chain lengths into drug molecules.
  • Synthesize lipophilic chains for improved drug delivery or bioavailability.
  • Serve as a precursor for building blocks in API synthesis.
  • Incorporate functionalities required for prodrug strategies.

When sourcing for pharmaceutical applications, it is imperative to buy 10-Chloro-1-Decanol from manufacturers who can guarantee the highest purity and a comprehensive Certificate of Analysis (CoA). A reliable 10-Chloro-1-Decanol supplier in China with strong quality control systems is invaluable for drug development pipelines.
