Description

3-(2-Hydroxyethoxycarbonyl)-5-(Sodiosulfo)Benzoic Acid is a functionalized benzoic acid derivative featuring both a hydrophilic sulfonate group and a hydroxyethoxycarbonyl moiety. This unique molecular structure makes it a valuable intermediate for synthesizing specialty chemicals with enhanced water solubility and reactivity. It is primarily sought after by manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries for the development of advanced formulations and active ingredients.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs), particularly those requiring enhanced solubility or specific ionic characteristics.
• Agrochemical Synthesis: Used in the production of modern herbicides, fungicides, and plant growth regulators where its polar groups aid in formulation stability and bioavailability.
• Dye & Pigment Manufacturing: Serves as a precursor for water-soluble dyes, reactive dyes, and high-performance pigments, leveraging its sulfonate group for colorant properties.
• Polymer Modification: Functional monomer for creating specialty polymers, ion-exchange resins, and coatings with improved hydrophilicity and adhesion properties.
• Surfactant & Detergent Industry: Intermediate for producing anionic surfactants and complexing agents used in industrial and institutional cleaning formulations.
• Research & Development: Valuable reagent in organic synthesis and material science research for introducing specific functional groups into complex molecules.

Quality Control

Our production of 3-(2-Hydroxyethoxycarbonyl)-5-(Sodiosulfo)Benzoic Acid adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency meet the high standards required for industrial and research applications. Certificates of Analysis (COA) detailing specific batch results are available upon request to support your quality assurance and regulatory compliance 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.
