Overview
Bromovanillin is a brominated derivative of vanillin, a naturally occurring compound found in vanilla beans. It is synthesized for its enhanced aromatic properties, making it valuable in the flavor and fragrance industries. The compound is also used as an intermediate in pharmaceutical synthesis. Due to its unique chemical structure, bromovanillin offers a more stable and intense aroma compared to vanillin. This makes it a preferred choice for high-end perfumery and specialty food flavorings. Its synthetic nature allows for consistent quality and supply, unlike natural vanillin which can vary based on crop conditions.
Physical and Chemical Properties
Bromovanillin appears as a white to pale yellow crystalline powder with a characteristic aromatic odor. It has a molecular weight of 231.05 g/mol and a melting point range of 163-165°C. The compound is soluble in organic solvents like ethanol and methanol but has limited solubility in water. Its bromine substitution enhances its stability and reactivity, making it useful in various chemical reactions. The presence of both aldehyde and hydroxyl groups allows it to participate in further chemical modifications, expanding its utility in synthetic applications.
Main Applications
The primary use of bromovanillin is in the flavor and fragrance industry, where it serves as a key ingredient in perfumes, soaps, and food flavorings. Its intense aroma and stability under heat make it ideal for baked goods and confectionery. In pharmaceuticals, bromovanillin acts as an intermediate in the synthesis of more complex molecules. Its bromine atom can be utilized in further chemical reactions, enabling the creation of specialized drugs and therapeutic agents. Research is ongoing into its potential applications in agrochemicals and other industrial uses.
Safety and Storage
Bromovanillin should be handled with care to avoid inhalation or skin contact, which can cause irritation. Personal protective equipment (PPE) such as gloves and goggles is recommended during handling. The compound should be stored in a cool, dry place away from direct sunlight and moisture to prevent degradation. In case of accidental exposure, rinse affected areas with plenty of water and seek medical attention if necessary. Proper ventilation is essential when working with bromovanillin to minimize the risk of airborne particles. Always refer to the material safety data sheet (MSDS) for detailed safety instructions.
B2B Procurement Guide
When procuring bromovanillin, verify the CAS number (2973-78-6) to ensure you are purchasing the correct compound. Check the purity specifications, which typically range from 98% to 99.5%, depending on the application. Reputable suppliers should provide certificates of analysis (COA) and material safety data sheets (MSDS). Consider the supplier's track record and certifications, such as ISO or GMP, to ensure quality and reliability. Bulk purchases may offer cost savings, but ensure proper storage conditions are maintained during transit and upon receipt. For reference, the price ranges between $50 and $100 per kilogram, though this can vary based on market conditions and order volume.
