o-Vanillin, also known as 2-hydroxy-3-methoxybenzaldehyde, is an organic compound with a chemical formula of \(C_{8}H_{8}O_{3}\) and a molecular weight of 152.15. It is an isomer of vanillin and is a white to slightly yellow crystalline powder with an aroma similar to vanillin, but with its own unique flavor.
From the perspective of chemical composition, o-vanillin is composed of three elements: carbon (C), hydrogen (H), and oxygen (O). Its molecular structure contains a benzene ring, to which is connected an aldehyde group (-CHO), a hydroxyl group (-OH), and a methoxy group (\(-OCH_{3}\)). These functional groups determine its chemical properties and aroma characteristics.
Spice industry: used to prepare various flavors, such as food flavors, daily chemical flavors, etc. In food flavors, it can be used in candies, baked goods, beverages, etc., giving the products unique aroma and flavor; in daily chemical flavors, it can be used in perfumes, detergents, skin care products, etc., adding unique fragrance to the products.
Organic synthesis: As an important organic synthesis intermediate, it can be used to synthesize compounds such as drugs, pesticides, dyes, etc. For example, it can be used to prepare drug intermediates with antibacterial, anti-inflammatory and other biological activities through a series of chemical reactions.
Electroplating industry: Adding o-vanillin to the electroplating solution can improve the quality and appearance of the electroplating layer, and improve the gloss and corrosion resistance of the electroplating layer.
Analytical reagents: It can be used as an analytical reagent for qualitative and quantitative analysis of certain compounds. For example, the characteristics of o-vanillin forming complexes with certain metal ions can be used to detect and determine the content of metal ions in the solution.
