Description

2-(Sulfooxy)Benzoic Acid is a versatile organic acid derivative, also known as salicylic acid sulfate, with significant utility in advanced chemical synthesis. Its unique sulfated structure makes it a valuable intermediate for creating more complex molecules in regulated industries where precise chemical functionality is required. This compound is essential for manufacturers and R&D teams in the pharmaceutical, agrochemical, and specialty chemical sectors seeking reliable, high-purity building blocks.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring sulfated phenolic groups.
• Agrochemical Synthesis: Used in the development of herbicides, fungicides, and plant growth regulators where the benzoic acid scaffold is functionalized.
• Biochemical Research: Serves as a substrate or inhibitor in enzymatic studies, particularly those involving sulfotransferases or esterases.
• Specialty Polymer Production: Acts as a monomer or modifying agent for creating polymers with specific ionic or hydrophilic properties.
• Dye and Pigment Manufacturing: Employed as an intermediate in the synthesis of sulfonated dyes and colorants.
• Cosmetic Ingredient Synthesis: Used in the controlled production of certain salicylate derivatives for topical applications.

Quality Control

Every batch of 2-(Sulfooxy)Benzoic Acid is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards for intermediates, with a focus on consistent purity and impurity profile. A comprehensive Certificate of Analysis (COA), detailing identity, assay, and specific impurity limits, is provided with each shipment to guarantee traceability and support your quality protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
