Description

2,2'-(Hydroxymethylimino)Diethanol is a versatile amino alcohol compound with a unique chemical structure that provides both hydroxyl and tertiary amine functionality. This dual reactivity makes it a valuable intermediate for the synthesis of specialty chemicals, including chelating agents, corrosion inhibitors, and polymer additives. It is particularly relevant for manufacturers in the lubricant, metalworking fluid, and personal care industries seeking to enhance product performance and stability.

Application

• As a key intermediate in the production of chelating agents and sequestrants for industrial water treatment.
• As a corrosion inhibitor component in metalworking fluids and lubricant formulations.
• As a building block for surfactants and emulsifiers used in personal care and cosmetic products.
• As a curing agent or crosslinker in epoxy resin and polyurethane systems.
• As a pharmaceutical intermediate for the synthesis of active ingredients and drug delivery agents.
• In the formulation of textile auxiliaries and dye-fixing agents.
• As a gas treating agent for the removal of acidic components like CO2 and H2S.

Quality Control

Our 2,2'-(Hydroxymethylimino)Diethanol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards and consistent performance. Certificates of Analysis (COA) documenting key parameters such as assay, identity, and impurity profiles are 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 room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and stability.
