Description

Catechol Sulfate CAS NO 4074-55-9 is an important organic sulfate ester derivative of catechol, serving as a key synthetic intermediate and research chemical. Its value lies in its role as a versatile building block for the development of more complex molecules in fine chemical synthesis. This compound is primarily needed by manufacturers and R&D laboratories in the pharmaceutical, agrochemical, and specialty chemical sectors for process development and analytical applications.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly where sulfate conjugation is a metabolic pathway.
• Biochemical Research: Serves as a reference standard or substrate in enzymatic studies related to sulfotransferase activity and sulfate metabolism.
• Fine Chemical Synthesis: Acts as a protected or functionalized precursor in multi-step organic synthesis for producing dyes, ligands, and complex organic molecules.
• Agrochemical Development: Employed in research for creating novel herbicides, pesticides, or plant growth regulators that utilize the catechol scaffold.
• Material Science: Investigated as a monomer or cross-linking agent in the development of specialty polymers and resins.

Quality Control

Our Catechol Sulfate is produced and tested under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters such as assay, impurity profile, and physical characteristics are provided and available upon request to support your quality assurance 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.
