4-Methylpentanoyl chloride(CAS: 38136-29-7)

4-Methylpentanoyl chloride (CAS: 38136-29-7) is a colorless liquid with a pungent odor. It has a molecular weight of approximately 142.16 g/mol and a boiling point of 63-65°C. This compound is poorly soluble in water but miscible with organic solvents. It is highly reactive, particularly towards nucleophiles and amines, making it useful in organic synthesis.

4-Methylpentanoyl chloride is typically synthesized by the reaction of 4-methylpentanoic acid with thionyl chloride. This process yields a high yield of the desired product. The reaction is usually carried out under anhydrous conditions to prevent hydrolysis and is catalyzed by thionyl chloride. The reaction is exothermic and requires careful temperature control to avoid side reactions.

4-Methylpentanoyl chloride (CAS: 38136-29-7) is primarily used in the pharmaceutical industry for the synthesis of certain drugs. It is also utilized in the production of polymers, sensors, and semiconductor materials. This compound serves as a key precursor in organic chemistry due to its reactivity and versatility in various chemical transformations.

When handling 4-Methylpentanoyl chloride (CAS: 38136-29-7), it is crucial to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to avoid inhalation. Spills should be immediately flushed with water, and the area should be cleaned with an appropriate solvent. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
