3.Application scope and Usage
2-Methylbutyric Acid is a natural short-chain fatty acid, mainly used in food flavors, pharmaceutical intermediates (for drug synthesis), feed additives (to attract animals), and cosmetic fragrances (perfumes, soap fragrances).
4.Package and Storage
2-Methylbutyric acid is packaged in 25kg HDPE plastic drums or aluminum drums. For food-grade products, nitrogen must be filled for protection. It should be stored in a cool, dark place (<25℃), sealed tightly to prevent oxidation, and kept away from strong alkalis and oxidants. Ventilation is required during operation (due to the pungent odor), and the shelf life is 24 months.
