Product Name:Proline
English Name:Proline
CAS No.:29795-82-2
Aliases:Pyrrolidine-2-carboxylic acid, 2-Pyrrolidinecarboxylic acid
Molecular Formula:C5H9NO2
Physical Properties:White crystalline powder with a slightly sweet taste; melting point about 228°C (decomposes); freely soluble in water, slightly soluble in ethanol, insoluble in ether; isoelectric point about 6.30.
Uses:Proline is the only cyclic secondary amino acid containing a pyrrolidine ring. It participates in protein synthesis and plays a role in osmotic regulation. In the pharmaceutical industry, it is used as an intermediate for the synthesis of drugs such as captopril. In agriculture, it is used in amino acid fertilizers and as a plant stress tolerance inducer to enhance resistance to drought, salinity, and other adverse conditions.
Technical Specifications:
Proline content (on dry basis): ≥99.0%
Melting point: 228–233°C (decomposition)
Loss on drying: ≤0.5%
Residue on ignition: ≤0.1%
Heavy metals (as Pb): ≤10 mg/kg
