Structure:


What is butyl acetate (cas 123 86 4) used for?
Coatings and paints: Butyl acetate serves as a key solvent/diluent for nitrocellulose, polyvinyl chloride (PVC), chlorinated rubber, and alkyd resins, used in automotive coatings, wood varnishes, architectural paints, and printing inks to improve film-forming, leveling, and drying properties.
Daily chemicals: Acts as a medium-boiling solvent in nail polish formulations and is blended with ethyl acetate to produce nail polish removers; it is also a common ingredient in fragrance products for its pleasant scent.
Pharmaceutical and chemical extraction: Functions as an extractant in petroleum refining and pharmaceutical manufacturing, particularly for isolating certain antibiotics and active pharmaceutical ingredients (APIs). It also acts as an analytical reagent for detecting elements like thallium, tin, tungsten, molybdenum, and rhenium in laboratory settings.
Food and flavor industry: N-Butyl Acetate is used as a flavoring agent to mimic fruity profiles (e.g., banana, pineapple, apricot) in food and beverage products, adhering to food-grade safety standards in regulated quantities.
