Description

Quinaldic Acid (CAS NO 93-10-7) is a versatile heterocyclic carboxylic acid that serves as a critical building block and analytical reagent in advanced chemical synthesis. Its unique molecular structure, featuring both a quinoline ring and a carboxylic acid group, makes it an essential precursor for creating complex molecules with specific functional properties. This high-purity intermediate is primarily utilized by the pharmaceutical, agrochemical, and specialty chemical industries for research, development, and manufacturing processes.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those with quinoline-based structures for antimicrobial or antimalarial applications.
• Metal Chelation & Analytical Chemistry: Used as a selective chelating agent for metal ions like copper and iron in analytical separations, gravimetric analysis, and spectrophotometric determinations.
• Agrochemical Synthesis: Building block for developing advanced fungicides, herbicides, and plant growth regulators within the crop protection sector.
• Ligand in Coordination Chemistry: Employed in the preparation of metal-organic frameworks (MOFs) and catalysts for organic transformations.
• Dye and Pigment Manufacturing: Intermediate in the production of specialized quinoline-derived dyes and colorants.
• Research & Development: Serves as a standard reagent and starting material in academic and industrial R&D labs for novel compound discovery.

Quality Control

Our Quinaldic Acid is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and related substances, to meet exacting customer specifications. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

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