Overview
Dihydrogeraniol is a monoterpenoid alcohol derived from geraniol, characterized by its floral and citrus-like aroma. It is a key ingredient in the fragrance and flavor industries due to its pleasant scent and stability. The compound is also used as an intermediate in the synthesis of other chemicals, including pharmaceuticals and agrochemicals. In nature, dihydrogeraniol is found in small quantities in essential oils such as rose and citronella. However, it is primarily produced synthetically for industrial applications. Its versatility and relatively low cost make it a popular choice for manufacturers seeking to add floral or citrus notes to their products.
Physical and Chemical Properties
Dihydrogeraniol is a colorless to pale yellow liquid with a density of 0.83 g/cm³ at 20°C. It has a boiling point of 212-214°C at standard pressure and is soluble in alcohol and ether but only slightly soluble in water. The compound is stable under normal conditions but should be protected from strong oxidizing agents. The molecular formula of dihydrogeraniol is C10H22O, and it has a molecular weight of 158.28 g/mol. Its key chemical properties include its ability to undergo esterification and oxidation reactions, making it useful in various synthetic processes. The compound’s floral, citrus-like odor is its most notable characteristic, which is why it is highly valued in perfumery and flavoring.
Main Applications
Dihydrogeraniol is predominantly used in the fragrance industry, where it serves as a key ingredient in perfumes, soaps, and detergents. Its floral and citrus notes make it ideal for creating fresh, uplifting scents. In the flavor industry, it is used to impart citrus-like flavors to food and beverages. Beyond fragrances and flavors, dihydrogeraniol is employed as an intermediate in the synthesis of other chemicals, including pharmaceuticals and agrochemicals. Its reactivity and stability under various conditions make it a versatile building block in organic synthesis. Additionally, it is sometimes used in cosmetic formulations for its pleasant aroma and mild properties.
Safety and Storage
Dihydrogeraniol is generally considered safe when handled properly, but it can cause skin and eye irritation upon contact. It is advisable to use personal protective equipment, such as gloves and goggles, when working with this chemical. Proper ventilation is also recommended to avoid inhalation of vapors. For storage, dihydrogeraniol should be kept in a cool, dry, well-ventilated area away from open flames and oxidizing agents. Containers should be tightly sealed to prevent contamination and evaporation. In case of spills, absorb with an inert material and dispose of according to local regulations.
B2B Procurement Guide
When procuring dihydrogeraniol, B2B buyers should prioritize suppliers who provide detailed product specifications, including purity levels and potential impurities. Certifications such as ISO or GMP can indicate a supplier’s reliability. Packaging options, such as drums or IBCs, should be chosen based on volume requirements and storage capabilities. Price negotiations should consider bulk purchase discounts, but buyers should also factor in logistics and handling costs. It is advisable to request samples for quality testing before committing to large orders. Additionally, buyers should verify the supplier’s ability to provide consistent quality and timely deliveries to avoid production disruptions.
