2-(Butylamino)ethanol CAS 111-75-1

N-Butylethanolamine CAS 111-75-1 for Organic Synthesis Intermediates

N-Butylethanolamine, also known as 2-(Butylamino)ethanol, is a secondary amino alcohol intermediate containing both butylamino and hydroxyl functionality. Its ethanolamine-derived structure makes it useful in organic synthesis routes where secondary amine structure, hydroxyethyl functionality and further derivatization are required.

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 a secondary amino alcohol building block for introducing butylaminoethyl 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 secondary amine structure, hydroxyl functionality, polarity adjustment or further functionalization is required.

• Ethanolamine derivative: The butylamino group and hydroxyethyl structure may support selected routes requiring amino alcohol chemistry, salt formation or hydroxyl-based derivatization.

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

• Further derivatization: The hydroxyl group and secondary amine functionality may be involved in acylation, alkylation, esterification, etherification, salt formation 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, odor, 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

N-Butylethanolamine is commonly handled as a liquid amino alcohol 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 secondary amino alcohol products, packaging tightness, odor control, moisture protection and compatibility with amine materials 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, oxidizing agents 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.

Related Applications

N-Butylethanolamine belongs to the ethanolamine and amino alcohol derivatives segment because of its secondary amino alcohol and hydroxyethyl structure. It is also related to tertiary amino alcohols and hindered amine bases where buyers compare other amino alcohol structures for organic synthesis.

This product is part of Aure Chemical’s broader amine derivatives for API synthesis and specialty chemical intermediates portfolio.
