(S)-(2-Aminomethyl)-1-N-Cbz-pyrrolidine, with the CAS number 119020-03-0, is a fine chemical that is a chiral amine with a carbobenzyloxy (Cbz) protecting group. The Cbz group is a commonly used protecting agent in organic synthesis to prevent amines from participating in unwanted reactions until the desired moment in a synthesis sequence.

This compound is particularly useful in the synthesis of pharmaceuticals and biologically active molecules where the stereochemistry at the amine center is important. The Cbz group can be selectively removed when needed, typically under mild acidic conditions, to reveal the free amine.

The molecule also contains a pyrrolidine ring, which is a common structural element in many natural products and pharmaceuticals. This ring, combined with the protected amine, makes the compound a valuable intermediate for the synthesis of a variety of complex molecules.

For more detailed information, including physical properties, chemical reactivity, and potential applications, one would typically refer to specialized chemical databases. The NIST Chemistry WebBook is one such resource that provides a wealth of data on compounds, including thermochemical data, spectral data, and more. Additionally, chemBlink is another database that can provide information on CAS-registered compounds, including safety data sheets (SDS) and information on suppliers.
