Description

2-Hydroxyisophthalicacid is a versatile aromatic dicarboxylic acid derivative, distinguished by the presence of a hydroxyl group on the benzene ring. This unique bifunctional structure makes it a valuable intermediate for synthesizing high-performance polymers, specialty resins, and complex organic molecules. It is essential for manufacturers and R&D laboratories in the pharmaceutical, agrochemical, and advanced materials sectors seeking to develop products with enhanced thermal stability, solubility, or specific chemical reactivity.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring specific carboxylic acid functionalities.
• Polymer & Resin Production: Monomer for creating specialty polyesters, polyamides, and liquid crystal polymers (LCPs) with improved mechanical and thermal properties.
• Agrochemical Synthesis: Intermediate in the manufacture of herbicides, fungicides, and plant growth regulators.
• Dye & Pigment Manufacturing: Used in the production of complex organic dyes and colorants.
• Metal Chelation & Coordination Chemistry: Serves as a ligand for metal ions in catalytic systems and metal-organic frameworks (MOFs).
• Research & Development: A crucial reagent in organic synthesis for academic and industrial R&D projects exploring new chemical entities.

Quality Control

Our 2-Hydroxyisophthalicacid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for demanding industrial and research applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment and is available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial use to prevent absorption of atmospheric moisture, which can affect product quality and handling.
