Cinnamic Acid
Description
Cinnamic Acid is an organic compound with the chemical formula C9H8O2. It is a white crystalline solid, slightly soluble in water but freely soluble in many organic solvents. Structurally, it consists of an acrylic acid group with a phenyl substituent at the 3-position, making it a monocarboxylic acid. It exists mainly in two isomeric forms, trans-cinnamic acid (the more common) and cis-cinnamic acid.
Physically, cinnamic acid appears as white to off-white monoclinic crystals with a melting point around 133-136 °C and a boiling point near 300 °C (where it decomposes). It has a density of about 1.247 g/cm³ and a characteristic honey-like odor. Cinnamic acid is naturally found in cinnamon oil, shea butter, and other plant sources.
Functionally, cinnamic acid is widely used in the production of flavorings, synthetic indigo, pharmaceuticals, and as a precursor in organic synthesis. Its molecular weight is approximately 148.16 g/mol, and it has a pKa around 4.44, reflecting its acidic nature. The compound is notable for its aromatic properties and its role in various chemical and industrial applications.
