4-Hydroxybenzaldehyde

Description:
4-Hydroxybenzaldehyde, also known as p-hydroxybenzaldehyde, is an aromatic compound characterized by the presence of both a hydroxyl group (-OH) and an aldehyde group (-CHO) attached to a benzene ring. Its molecular formula is C7H6O2, and it features a phenolic structure, which contributes to its reactivity and solubility properties. This compound is typically a white to light yellow crystalline solid with a distinct aromatic odor. It is soluble in organic solvents such as ethanol and ether, but only slightly soluble in water due to its hydrophobic benzene ring. 4-Hydroxybenzaldehyde is used in various applications, including as an intermediate in the synthesis of pharmaceuticals, dyes, and fragrances. Additionally, it exhibits antioxidant properties and can participate in various chemical reactions, such as electrophilic aromatic substitution and condensation reactions. Safety precautions should be taken when handling this compound, as it may cause irritation to the skin, eyes, and respiratory system.
