Can I get [R]-Pyrrolidine-3-carboxylic acid ethyl ester HCL in a different salt form or as the free base?
Yes. ChemContract Research can supply [R]-Pyrrolidine-3-carboxylic acid ethyl ester HCL as the free base or convert it to alternative salt forms including hydrochloride, mesylate, tosylate, fumarate, or other pharmaceutically acceptable counter-ions. Salt form selection impacts crystallinity, stability, and solubility — our chemistry team can advise on optimal salt selection for your application. Currently supplied as the Hydrochloride form.
What coupling reagents work best with [R]-Pyrrolidine-3-carboxylic acid ethyl ester HCL?
For amide bond formation from the carboxylic acid in [R]-Pyrrolidine-3-carboxylic acid ethyl ester HCL, HATU/DIPEA is recommended for peptide coupling (high yield, low epimerization). EDC/HOBt is a cost-effective alternative for non-peptide amides. T3P (propylphosphonic acid anhydride) offers excellent atom economy with easy workup. For ester formation, DCC/DMAP (Steglich conditions) or Mitsunobu conditions are standard.
How should I store [R]-Pyrrolidine-3-carboxylic acid ethyl ester HCL?
Store at room temperature in a tightly sealed container. Protect from moisture and strong bases. Store at room temperature in a tightly sealed container away from heat and open flame. Store at room temperature in a tightly sealed container. Protect from humidity. Always consult the compound-specific Safety Data Sheet (SDS) provided with your order for detailed storage requirements. ChemContract Research includes handling and storage documentation with every shipment.
