Applications
Pharmaceutical Industry
Pharmaceutical Intermediates:
Key raw material for synthesizing antidepressants (e.g., milnacipran), anticonvulsants, and local anesthetics (e.g., piperocaine);
Used in the preparation of ACE inhibitor antihypertensive drugs.
Drug Carrier: Its polarity and solubility make it a cosolvent for injections or a component of sustained-release formulations.
Organic Synthesis
Solvent: High boiling point and strong polarity, used for dissolving polar organic compounds (e.g., as a reaction medium in polymer synthesis);
Chiral Synthesis: Acts as a chiral auxiliary or ligand in asymmetric synthesis reactions (e.g., Michael addition, Diels-Alder reaction).
Agriculture and Daily Chemicals
Pesticide Intermediates: Synthesis of herbicides and insecticides (e.g., heterocyclic pesticides containing piperidine structures);
Surfactants: Reacts with fatty acids to form amide-based surfactants for detergents or emulsifiers.
Materials Science
Polymer Additives: Improves the flexibility and thermal stability of polyamides (nylons);
Ionic Liquid Precursor: Prepares functional ionic liquids via alkylation for catalysis or energy storage.
Safety and Storage
Hazards:
Irritant: Stimulates skin, eyes, and respiratory tract; high-concentration inhalation may cause headache and nausea;
Low Toxicity: LD50 (rat, oral) ~2000 mg/kg, classified as a low-toxic compound.
Safety Measures:
Wear gloves and goggles during operation; use in a well-ventilated area;
If skin contact occurs, rinse with soapy water immediately; if ingested, drink warm water to induce vomiting and seek medical attention.
Storage Conditions:
Store in a sealed container in a cool, dry place, away from oxidizers and strong acids, and protect from moisture.
