What Is N-Butylethanolamine (NBEA)?
N-Butylethanolamine (NBEA), also known as 2-(Butylamino)ethanol, is a secondary alkanolamine with the molecular formula C₆H₁₅NO and CAS number 111-75-1. Its structure combines a butyl group (C₄H₉–) and a hydroxyl-bearing ethyl arm (–CH₂CH₂OH) on a single secondary nitrogen, giving it the dual character of an amine and an alcohol simultaneously.
NBEA is a clear, colorless to pale yellow liquid at room temperature with a characteristic amine odor. It has a melting point well below −60 °C (remaining liquid in virtually all storage conditions), a boiling point of 195–198 °C, and a flash point of ~78 °C. It is fully miscible with water, ethanol, and common organic solvents.
As a secondary alkanolamine, NBEA offers moderate alkalinity, excellent hydrophilicity, and high reactivity toward alkylation, acylation, and condensation reactions. This versatile reactivity profile makes it a valuable intermediate in pharmaceutical API synthesis, agrochemical formulations, surfactant manufacturing, rubber and plastics processing, metalworking fluids, and textile auxiliaries. SinoLook Chem supplies NBEA at ≥99.0% purity from ISO 9001-certified manufacturing facilities.

Frequently Asked Questions
Common technical and commercial questions about N-Butylethanolamine from our B2B customers worldwide.
What is N-Butylethanolamine (NBEA) and what is it used for?
N-Butylethanolamine (NBEA, CAS 111-75-1) is a secondary alkanolamine with the formula C₆H₁₅NO, also known as 2-(Butylamino)ethanol. It is used as a chemical intermediate in pharmaceutical API synthesis (antihistamines, antihypertensives), as a neutralizer and emulsifier in agrochemical formulations, as a raw material for non-ionic and cationic surfactants, as a corrosion inhibitor in metalworking fluids, and as a curing agent or plasticizer additive in rubber and plastics processing.
What purity grade does SinoLook Chem supply for NBEA?
SinoLook Chem supplies N-Butylethanolamine at ≥99.0% purity (GC assay), with typical batch results of 99.5–99.8%. Water content is ≤0.3% (typically 0.10–0.15%) and color is ≤20 APHA (typically ≤10). A full Certificate of Analysis (CoA) covering all specification parameters is issued with every shipment. Pharmaceutical-grade documentation including compliance letters is available on request.
What is the difference between NBEA and MEA / DEA / TEA?
MEA, DEA, and TEA (the ethanolamine family) all have hydroxyethyl groups on nitrogen and are produced from ethylene oxide and ammonia. NBEA differs in that it has a butyl (C₄H₉–) substituent rather than a hydroxyethyl group, making it a secondary amine with more hydrophobic character. This gives NBEA better compatibility with organic media and different reactivity in condensation and alkylation chemistry. NBEA is not primarily used for gas sweetening (unlike MEA/DEA) but is valued as a synthetic building block in fine chemicals and formulation chemistry.
What are the storage and handling requirements for NBEA?
NBEA has a flash point of ~78 °C and should be stored as a flammable liquid: in a cool (5–35 °C), well-ventilated area away from heat sources, sparks, and open flames. Keep away from strong acids, oxidizers, and acid chlorides. Use stainless steel or HDPE containers; avoid copper and copper alloys. Wear chemical-resistant gloves (nitrile or butyl rubber), safety goggles, and a face shield when handling. Work in a ventilated area or use respiratory protection if mist or vapor may be generated.
What is the N-Butylethanolamine HS code?
N-Butylethanolamine (CAS 111-75-1) is classified under HS code 2922.19 (amino alcohols - other, other than those only containing oxygen-containing groups as heteroatoms, their ethers and esters; salts thereof). Always confirm the applicable tariff code with your local customs authority, as classifications can vary by jurisdiction.
What is the N-Butylethanolamine price?
NBEA pricing depends on order volume, packaging format, and delivery terms. Volume discounts are available starting from 500 kg regular orders, with fixed-price contract options for long-term buyers of 5,000+ kg.
