Cas no 100-09-4 (p-Anisic acid)

Technical Introduction: p-Anisic Acid p-Anisic acid (4-methoxybenzoic acid) is a white crystalline organic compound with the molecular formula C?H?O?. It is widely used as an intermediate in pharmaceutical, fragrance, and agrochemical synthesis due to its methoxy-substituted aromatic structure. The compound exhibits antimicrobial properties, making it valuable in preservative formulations. Its solubility in organic solvents and moderate acidity facilitate its incorporation into various chemical processes. p-Anisic acid is also employed in the production of liquid crystal materials and UV stabilizers. High purity grades ensure consistent performance in sensitive applications. Stability under standard storage conditions and well-documented reactivity further enhance its utility in industrial and research settings.
