Description

m-Tolyldiethanolamine is a versatile aromatic amine derivative with a diethanolamine functional group, serving as a key intermediate in advanced organic synthesis. Its structure makes it valuable for introducing both aromatic and hydrophilic amine-alcohol moieties into target molecules. This compound is essential for manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to develop products with specific functional properties.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a toluidine-based backbone with solubilizing hydroxyl groups.
• Agrochemical Synthesis: Acts as a building block for herbicides, fungicides, and plant growth regulators, where its aromatic amine group is crucial for biological activity.
• Corrosion Inhibitor Formulation: Employed in the production of additives for metalworking fluids and industrial coolants due to its amine functionality.
• Polymer & Resin Modifier: Serves as a monomer or cross-linking agent in the production of epoxy hardeners, polyurethanes, and other specialty polymers to enhance flexibility and adhesion.
• Dye & Pigment Manufacturing: Utilized as a precursor in the synthesis of complex organic dyes and pigments, leveraging the toluidine ring for color development.
• Surfactant & Emulsifier Production: Functions as a raw material for synthesizing non-ionic surfactants with specific hydrophilic-lipophilic balance (HLB) properties.

Quality Control

Our m-Tolyldiethanolamine is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets the high-purity standards required for sensitive synthetic applications. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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.
