Description

Thiosalicylic Acid CAS NO 7283-41-2 is a sulfur-containing derivative of salicylic acid, serving as a versatile organic intermediate and building block in advanced chemical synthesis. Its unique structure, featuring both a carboxylic acid and a thiol group, makes it a critical precursor for synthesizing heterocyclic compounds, metal chelators, and functional polymers. This compound is essential for research and production in the pharmaceutical, agrochemical, and specialty chemical industries, where it is used to develop active ingredients, ligands, and novel materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), thiazole-containing drug candidates, and other bioactive molecules.
• Agrochemical Synthesis: Used in the production of fungicides, herbicides, and plant growth regulators that require a thiosalicylate core structure.
• Chemical Research & Development: Employed as a versatile reagent in organic synthesis, particularly for creating sulfur heterocycles and as a ligand precursor in coordination chemistry.
• Polymer & Material Science: Acts as a monomer or modifier in the production of specialty polymers, resins, and functional materials with specific chemical properties.
• Analytical Chemistry: Utilized as a derivatization agent or a standard in chromatographic analysis and other laboratory testing procedures.
• Dye & Pigment Manufacturing: Serves as an intermediate in the synthesis of certain sulfur dyes and organic pigments.

Quality Control

Our Thiosalicylic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for industrial and research applications. We provide full traceability and Certificates of Analysis (COA) are available upon request, detailing key parameters such as assay, identity, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its properties of being easily oxidized (store under inert atmosphere) and light-sensitive, prolonged exposure to air, moisture, or light should be avoided to maintain product integrity.
