3.Application scope and Usage
Heptanoic Acid is an important organic acid, mainly used in food flavors (for blending cheese and butter flavors, FEMA 3348), pharmaceutical intermediates (for synthesizing steroid hormones), industrial lubricants (as a basic raw material for ester synthesis), and cosmetics (as a fragrance fixative). Its unique fatty acid properties make it widely applicable in the fields of food, medicine, and chemicals.
4.Package and Storage
Gentianic acid is packaged in 25kg HDPE plastic drums or aluminum drums. For food-grade use, it needs to be protected by nitrogen. It should be stored in a cool, dark place (< 25℃), sealed tightly to prevent oxidation, and kept away from alkalis and oxidants. During operation, ventilation is required (due to the pungent smell), and the shelf life is 24 months.
