For professionals in the chemical and pharmaceutical industries, a deep understanding of a compound's physical and chemical properties is fundamental to its effective utilization. 4-Phenylbutan-1-ol, identified by CAS number 3360-41-6, is a prime example of a chemical intermediate whose properties are critical for its application, particularly in the synthesis of important pharmaceuticals like Salmeterol.

This compound, also known as phenylbutyl alcohol, presents as a clear, colorless to pale yellow liquid. This visual characteristic is the first step in identifying its state and purity. Its molecular formula, C10H14O, reveals its composition of carbon, hydrogen, and oxygen atoms, while its molecular weight of approximately 150.22 g/mol is a key parameter for stoichiometric calculations in chemical reactions. These basic identifiers are crucial for chemists and process engineers.

Delving deeper into its physical properties, 4-Phenylbutan-1-ol has a density of around 0.984 g/mL at 20°C, indicating it is slightly less dense than water. Its boiling point is reported as 140-142°C at 14 mm Hg, a value that is significantly lower than its boiling point at atmospheric pressure, suggesting it is amenable to distillation under reduced pressure for purification. Its flash point, being greater than 230°F, classifies it as a combustible liquid, necessitating appropriate safety precautions during handling and storage, a detail emphasized by NINGBO INNO PHARMCHEM CO.,LTD. in their material safety data.

Chemically, 4-Phenylbutan-1-ol is a stable compound, though it is incompatible with strong oxidizing agents. This stability, coupled with its reactivity as a primary alcohol, makes it a versatile building block in organic synthesis. The presence of the phenyl group and the hydroxyl functional group allows for a range of chemical transformations, including esterification, etherification, and oxidation reactions, all vital for constructing more complex molecules required in pharmaceutical development.

Understanding these chemical properties is not just academic; it directly impacts the efficiency and safety of manufacturing processes. By providing materials with clearly defined specifications, such as the purity and reactivity profiles of 4-Phenylbutan-1-ol, NINGBO INNO PHARMCHEM CO.,LTD. supports the broader goal of producing safe and effective medicines. The meticulous characterization of such intermediates is a testament to the precision required in pharmaceutical chemistry.
