Overview
4-Dimethoxybenzaldehyde, commonly known as veratraldehyde, is an organic compound belonging to the class of aromatic aldehydes. It is characterized by the presence of two methoxy groups attached to a benzene ring, which enhances its utility in various chemical syntheses. The compound is primarily used as an intermediate in the production of pharmaceuticals, fragrances, and other specialty chemicals. Veratraldehyde is synthesized through the oxidation of veratrole or by other chemical processes involving methoxy-substituted benzaldehydes. Its unique aromatic properties make it a valuable ingredient in the flavor and fragrance industry, where it imparts a sweet, vanilla-like odor.
Physical and Chemical Properties
4-Dimethoxybenzaldehyde appears as a white to pale yellow crystalline powder with a characteristic aromatic odor. It has a molecular weight of 166.17 g/mol and a density of 1.12 g/cm³. The compound melts at 40-43 °C and boils at 281-285 °C, making it stable under typical storage conditions. Solubility-wise, veratraldehyde is highly soluble in organic solvents such as ethanol, ether, and benzene, but only slightly soluble in water. Its chemical structure includes a reactive aldehyde group, which allows it to participate in various condensation and oxidation reactions, making it a versatile intermediate in organic synthesis.
Main Applications
Veratraldehyde is widely used in the pharmaceutical industry as an intermediate for the synthesis of drugs such as antihypertensives and antimicrobial agents. Its role in the fragrance industry is equally significant, where it serves as a precursor for vanilla-like scents and other aromatic compounds. In addition, 4-Dimethoxybenzaldehyde finds applications in agrochemicals and dyes. Its ability to undergo various chemical transformations makes it a key building block in the synthesis of complex organic molecules. The compound's versatility and stability contribute to its widespread use in research and industrial applications.
Safety and Storage
4-Dimethoxybenzaldehyde should be handled with care due to its potential to irritate the skin, eyes, and respiratory system. Appropriate personal protective equipment, including gloves and goggles, is recommended when working with this chemical. Storage conditions should include a cool, dry place away from direct sunlight and moisture to prevent degradation. The compound should be kept in tightly sealed containers to avoid exposure to air and contaminants. Proper labeling and adherence to safety protocols are essential to ensure safe handling and storage.
B2B Procurement Guide
When procuring veratraldehyde, it is crucial to verify the supplier's credentials and request a Certificate of Analysis (COA) to ensure product quality and purity. The Material Safety Data Sheet (MSDS) should also be reviewed to understand handling and safety requirements. Price ranges for 4-Dimethoxybenzaldehyde vary depending on purity levels and order quantities, typically ranging from $50 to $100 per kilogram. Bulk purchases may offer cost advantages, but buyers should also consider logistics and storage capabilities. Establishing long-term relationships with reliable suppliers can help secure consistent quality and competitive pricing.
