3.Ámbito de aplicación y uso
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.Embalaje y almacenamiento
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.
