Description

Potassium Ethyl 4-Oxidobenzoate is a potassium salt derivative of ethyl 4-hydroxybenzoate, a compound of significant interest in fine chemical synthesis. This material serves as a versatile and reactive intermediate, prized for its enhanced solubility and stability in various reaction media compared to its acid counterpart. It is primarily utilized by manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for the development of active ingredients, UV absorbers, and polymer additives.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring a protected phenolic moiety.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where the benzoate structure is integral.
• Polymer Additives: Acts as a precursor for light stabilizers and antioxidants incorporated into plastics and coatings to enhance durability.
• Organic Synthesis Reagent: Employed in laboratory and industrial-scale organic reactions, including esterifications and etherifications, as a soluble salt form.
• UV Absorber Production: Intermediate in the manufacturing of organic compounds used in sunscreens and materials requiring UV protection.
• Preservative Precursor: Starting material for the synthesis of paraben-based preservative compounds.

Quality Control

Our Potassium Ethyl 4-Oxidobenzoate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting results for assay, related substances, and other critical parameters are provided with every shipment to guarantee traceability and batch-to-batch consistency for your formulation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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 after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
