O-Anisidine, chemically known as 2-methoxyaniline or ortho-anisidine (CAS 90-04-0), is a fundamental organic compound with a distinctive profile of chemical properties that make it invaluable across several industrial sectors. As a supplier of this essential intermediate, understanding its characteristics is key to appreciating its broad applicability.

Physically, O-Anisidine presents as a light red or light yellow oily liquid. Its molecular formula is C7H9NO, and it has a molecular weight of approximately 123.15 g/mol. A key characteristic is its purity, with standard specifications often exceeding 99%. This high purity is critical for its downstream applications, particularly in the synthesis of sensitive compounds.

Chemically, O-Anisidine is an aromatic amine featuring a methoxy group ortho to the amino group on a benzene ring. This structure dictates its reactivity. It is soluble in dilute mineral acids, ethanol, and ether, but only slightly soluble in water. The compound can darken upon exposure to air, indicating sensitivity to oxidation, a factor that manufacturers must consider during storage and handling. Its boiling point is around 225 °C, and its melting point is typically between 3-6 °C, classifying it as a liquid under standard room temperature conditions.

The applications of O-Anisidine are diverse and significant. Primarily, it serves as a crucial dye intermediate, contributing to the vibrant hues found in azo dyes and pigments used extensively in the textile, paint, and ink industries. Its utility extends to the pharmaceutical synthesis sector, where it acts as a precursor for various active pharmaceutical ingredients (APIs) and drug intermediates. Furthermore, O-Anisidine finds application in the food industry, notably in the production of vanillin, a key flavoring agent.
