In the vast landscape of organic chemistry, certain compounds serve as foundational elements, enabling the creation of countless advanced materials and products. 3-Hydroxybenzoic Acid (CAS 99-06-9) is one such pivotal molecule, widely recognized for its versatility as a fine chemical intermediate. Its unique combination of a carboxyl group and a hydroxyl group on a benzene ring bestows upon it a reactivity profile that is invaluable across multiple industries. As a dedicated manufacturer and supplier, we understand the importance of detailing these aspects for our B2B clientele.

The synthesis of 3-Hydroxybenzoic Acid is a well-established process, often starting from benzoic acid. Traditional methods involved sulfonation, alkali fusion, and acidification, though these are being superseded by more environmentally friendly and efficient routes. Modern processes often utilize m-cresol as a raw material, employing protection-oxidation-hydrolysis sequences. This refined production pathway ensures high purity and yield, critical factors for its use in demanding applications such as pharmaceutical synthesis and the creation of specialty chemicals. Understanding the production process allows buyers to appreciate the quality they can expect when they purchase.

The chemical properties of 3-Hydroxybenzoic Acid are key to its broad utility. It presents as a white crystalline powder with a melting point typically around 200-203°C, indicating good thermal stability. Its solubility in polar organic solvents like DMSO and methanol, albeit slight, is sufficient for many reaction chemistries. Crucially, it exhibits a distinct acidity, being stronger than its ortho and para isomers, which influences its behavior in various chemical reactions. This predictable chemical behavior is a significant advantage for R&D scientists and formulators.

The applications of 3-Hydroxybenzoic Acid are diverse and far-reaching. Its primary role as a pharmaceutical intermediate is well-documented, aiding in the development of active pharmaceutical ingredients. Furthermore, it serves as a building block for agrochemicals and is essential in the synthesis of azo dyes, contributing to vibrant and stable coloration. Beyond synthesis, its inherent fungicidal and preservative properties make it a valuable additive, extending product life and preventing degradation. As a plasticizer, it enhances material flexibility. When seeking to buy this compound, considering its multifaceted applications can unlock new avenues for product development.
