Product Name: L-Proline
CAS No.: 147-85-3
Molecular Formula: C5H9NO2
Standarad: AJI92, USP24, USP30, USP31
Package: 25kgs/ fiber drum
Application:
Proline and its derivatives are often used as asymmetric catalysts in organic reactions. The CBS reduction and proline catalysed aldol condensation are prominent examples.
L-Proline is an osmoprotectant and therefore is used in many pharmaceutical, biotechnological applications.
In brewing, proteins rich in proline combine with polyphenols to produce haze (turbidity).
