Z-Glu(OtBu)-Gly-OH·DCHA is a protected Glu-Gly dipeptide supplied as a dicyclohexylammonium salt. Cbz protects the N-terminus and OtBu protects the glutamate side-chain carboxyl.
The DCHA counterion is part of the supplied material and should be included when calculating equivalents or interpreting molecular weight.
Product Information
| Product Name | Z-Glu(OtBu)-Gly-OH·DCHA |
| Catalog No. | AS4131 |
| Molecular Formula | C31H49N3O7 |
| Molecular Weight | 575.75 g/mol |
| Material / Building Block Type | Cbz-Glu(OtBu)-Gly dipeptide dicyclohexylammonium salt |
| Primary Applications | Solution-phase peptide fragment synthesis; protected acidic dipeptide chemistry; Cbz-compatible coupling; counterion-controlled intermediate handling |
Application Scope in Solution-Phase Fragment Chemistry
The Cbz/Glu(OtBu) protection pattern is useful in solution-phase and protected-fragment routes where reductive N-deprotection and acid-labile side-chain deprotection provide complementary control.
Counterion and Deprotection Planning
DCHA can affect solubility and reagent-equivalent calculations. Cbz is typically removed reductively, whereas OtBu is acid-labile; the route should be checked for reducible or acid-sensitive groups before fragment use.
Procurement and QC
Confirm Glu-Gly sequence, L-Glu stereochemistry, Cbz/OtBu protection and DCHA salt identity using lot-specific documentation.
Use the lot-specific COA to confirm salt stoichiometry before scale-up or quantitative solution preparation.
