Description
Glycine anhydride is an extra pure cyclic dipeptide with the empirical formula C₄H₆N₂O₂ and CAS number 106-57-0. Also known as 2,5-diketopiperazine, it has a molar mass of 114,10 g/mol and serves as a compact, well-defined building block in peptide-related and heterocyclic chemistry. The extra pure grade supports laboratory work that needs a clean diketopiperazine core for synthesis, reference standards or mechanistic studies. Supplied in a 25 g plastic pack, the solid is practical for repeated small-scale use in organic and bio-organic laboratories. This quality material from manufacturer Carl ROTH is suited to research on peptide mimics, condensation chemistry and nitrogen-heterocycle routes. Its defined composition and molar mass facilitate stoichiometric planning and analytical comparison. Intended for professional laboratory applications in chemical synthesis, method development and related scientific workflows where glycine-derived cyclic amides are required.
