Propylamine
Description
Propylamine (CAS 107-10-8) is a primary aliphatic amine used as a reactive intermediate and pH modifier across pharmaceutical, polymer, and flavor chemistry. With FEMA 4237 status, it is also recognized in flavor applications under regulated conditions.
Its reactivity toward carbonyl compounds, acids, and isocyanates makes it a building block for a broad range of synthesized end products. In pharmaceutical manufacturing, it serves as an intermediate in the synthesis of active ingredients.
It is particularly useful for antihistamines and cardiovascular compounds. Polymer producers use it as a curing agent and cross-linker for epoxy systems, where amine reactivity directly influences cure rate and final mechanical properties.
In flavor formulation, it contributes to specific aroma profiles at controlled concentrations under FEMA guidelines. Personal care chemists incorporate it as a pH buffer and neutralizing agent in formulations requiring precise alkalinity control.
Propylamine is supplied as a liquid, typically at high purity grades suited to pharmaceutical and industrial synthesis. Technical grade is standard for polymer and chemical manufacturing applications across various industries.
Pharmaceutical-grade material is available where API synthesis or regulated flavor use requires tighter specification and documentation. This ensures compliance with rigorous safety and quality standards for sensitive chemical processes.
