3-diethylamino-1,2-propanediol CAS 621-56-7

3-Diethylamino-1,2-propanediol CAS 621-56-7 for Organic Synthesis Intermediates

3-Diethylamino-1,2-propanediol is an N-substituted aminopropanediol intermediate containing both tertiary amine and vicinal diol functionality. Its combined amino alcohol and diol structure makes it useful in organic synthesis routes where hydroxy-functional tertiary amine building blocks are required for further derivatization.

This product may be used in pharmaceutical intermediate synthesis, fine chemical synthesis, specialty organic intermediate preparation and downstream amine- or hydroxyl-based transformations. In B2B sourcing, buyers usually need to confirm assay, water content, appearance, color, related amine impurities, residual solvents, storage conditions, packaging, transport classification and documentation availability before purchase.

Chemical Structure

Key Applications

• Organic synthesis intermediate: Used as an N-substituted amino diol building block for introducing both tertiary amine and hydroxyl functionality in downstream synthesis.

• Pharmaceutical intermediate synthesis: May be used as a starting material or intermediate in selected pharmaceutical intermediate routes, subject to specification and process requirements.

• Fine chemical intermediate: Suitable for specialty chemical synthesis where hydroxy-functional tertiary amine structure, polarity adjustment or further functionalization is required.

• N-substituted aminopropanediol intermediate: The diethylamino group and vicinal diol structure may support selected routes requiring modified basicity, steric environment or multifunctional amine alcohol chemistry.

• R&D and process evaluation: Can support laboratory evaluation, route screening and process development for organic synthesis projects.

• Further derivatization: The hydroxyl groups and tertiary amine functionality may be involved in salt formation, esterification, etherification, protection/deprotection or other downstream transformations depending on the synthesis route.

Sourcing and Documentation Support

• Specification confirmation: Assay, appearance, color, water content, related amine impurities, residual solvents and physical state can be reviewed according to buyer requirements and supplier confirmation.

• COA and SDS support: COA and SDS may be provided for confirmed products, subject to product, batch and supplier confirmation.

• Packaging review: Packaging options can be checked according to product properties, order quantity, moisture sensitivity, storage requirements and transport classification.

• Export and logistics discussion: Shipment feasibility, dangerous goods classification, trade term and destination requirements should be confirmed case by case before quotation or shipment.

Packaging and Logistics Considerations

3-Diethylamino-1,2-propanediol is commonly handled as a liquid material. Suitable packaging should be confirmed according to product properties, order quantity, storage conditions, supplier specification and transport route.

Packaging may include small bottles, small drums, 25 L drums, 200 L drums or other suitable formats, subject to supplier confirmation. For hydroxy-functional amine products, packaging tightness, moisture protection and storage conditions should be reviewed before shipment.

Sea, air, courier, LCL or FCL shipment feasibility should be evaluated case by case according to the latest SDS, transport classification, package size and destination requirements. Import clearance, local duties, taxes and destination compliance should be confirmed by the buyer or their appointed import agent.

Common trade terms may include FOB China port, FCA warehouse, CFR/CIF destination port or DAP destination where applicable. Final shipment arrangement depends on product classification, order quantity, destination and buyer import capability.

Safety and Storage Information

The following safety information is for general reference only. Final hazard classification, handling requirements, storage conditions and transport conditions must be confirmed according to the latest SDS and shipment documents.

• Handling: Handle in a well-ventilated area with appropriate personal protective equipment and avoid direct contact with skin, eyes and clothing.

• Storage: Keep the container tightly closed and store in a cool, dry and well-ventilated place. Protect from moisture, heat and incompatible materials.

• Transport confirmation: Transport classification, labels and packaging requirements should be verified according to the latest SDS, dangerous goods classification report or shipment documents.
