Description

2-Cbz-Amino-Ethanesulfonic Acid is a specialized organic building block featuring both a carboxybenzyl (Cbz) protecting group and a sulfonic acid moiety. This compound is of significant value in synthetic organic chemistry, particularly for the protection of amines and the introduction of sulfonate functionality into target molecules. It is primarily utilized by researchers and manufacturers in the pharmaceutical and fine chemical industries for the development of novel active pharmaceutical ingredients (APIs) and complex intermediates.

Application

• Pharmaceutical Intermediate: A key building block in the multi-step synthesis of complex drug candidates and active pharmaceutical ingredients (APIs).
• Peptide Chemistry: Used for the temporary protection of amino groups during solid-phase and solution-phase peptide synthesis.
• Sulfonation Agent: Serves as a reagent to introduce water-solubilizing sulfonate groups into organic molecules.
• Bioconjugation: Employed in the development of linker molecules for antibody-drug conjugates (ADCs) and other bioconjugates.
• Chemical Biology Research: Utilized as a tool compound in proteomics and enzyme inhibition studies.
• Fine Chemical Synthesis: Acts as a precursor for the preparation of specialty surfactants and functional materials.
