Diethylpropylamine[2]
Overview
Diethylpropylamine is a tertiary amine with the chemical formula C7H17N, structurally composed of a propyl group bonded to a nitrogen atom flanked by two ethyl groups. It is primarily employed as a building block in organic synthesis and pharmaceutical manufacturing. As a volatile liquid with a pungent odor, it serves as a versatile intermediate for quaternary ammonium compounds and specialty surfactants. Its reactivity stems from the lone electron pair on nitrogen, enabling participation in alkylation and acylation reactions.
Physical and Chemical Properties
Diethylpropylamine is characterized by a low boiling point (110-112°C) and density (0.74 g/cm³), typical of small tertiary amines. It is miscible with most organic solvents but exhibits limited water solubility due to its hydrophobic alkyl chains. The compound’s basicity (pKa ~10.5) allows it to act as a nucleophile or catalyst in reactions. It is sensitive to oxidation and should be stored under inert atmospheres to prevent degradation. Its flammability (flash point ~15°C) necessitates careful handling.
Main Applications
In pharmaceuticals, diethylpropylamine is a precursor for antihistamines and local anesthetics. Its nitrogen center facilitates the formation of active pharmaceutical ingredients (APIs) through quaternization or salt formation. Industrial uses include corrosion inhibition in oilfield chemicals and as a catalyst in polyurethane production. It also finds niche applications in agrochemical synthesis and as a ligand in coordination chemistry.
Safety and Storage
Diethylpropylamine requires strict safety measures due to its flammability and irritant properties. Storage should be in tightly sealed containers, away from heat sources and oxidizers, at temperatures below 25°C. Personal protective equipment (PPE) such as nitrile gloves, goggles, and respirators are mandatory during handling. Spill management involves neutralization with dilute acids and absorption with inert materials like sand.
B2B Procurement Guide
Bulk purchasers should prioritize suppliers offering ≥98% purity with analytical certificates (COA). Packaging options range from 1L glass bottles to 200L steel drums, depending on scale. Key due diligence includes verifying regulatory compliance (REACH, TSCA) and evaluating logistics for hazardous material transport. Spot prices fluctuate with raw material (propylene, ethylamine) costs; long-term contracts may stabilize pricing.
