Introduction
7-Hydroxyvanillin is an organic compound. It is a colorless to light yellow liquid with a distinctive aroma, similar to the scent of vanilla and tobacco. The preparation of 7-hydroxyvanillin is usually achieved through the hydroxylation of vanillin. A common synthesis method involves using hydrogen peroxide and a cobalt catalyst to catalyze the reaction under appropriate temperature and pressure, converting the aldehyde group in vanillin to a hydroxyl group. 7-Hydroxyvanillin is relatively safe under normal use conditions. At high concentrations, it may cause irritation to the skin and eyes. When handling this compound, necessary safety measures should be taken, such as wearing gloves and goggles. In use, it is important to avoid inhalation or ingestion to prevent adverse health effects.
