Compound comparison
CJC-1295 (DAC) vs Ipamorelin · Component Comparison
Both peptides are present in our CJC/IPA reference blend, but they are mechanistically and structurally distinct. This comparison breaks down each component's specifications.
Shared characteristics
- ·Both are GH-axis research reference compounds frequently co-studied
- ·Both supplied lyophilized in our single-vial CJC/IPA blend at ≥99% individual purity
- ·Both confirmed by ESI-MS for identity
- ·Both ship under the same blend COA documenting individual purities
Side-by-side differences
| Aspect | CJC / IPA | CJC / IPA |
|---|---|---|
| Class | GHRH analog (30-residue) | GH secretagogue pentapeptide |
| Residue count | 30 + DAC moiety | 5 residues, C-terminal amide |
| Molecular weight | 3367.7 g/mol | 711.85 g/mol |
| Molecular formula | C152H252N44O42 | C38H49N9O5 |
| CAS number | 863288-34-0 | 170851-70-4 |
| Distinguishing feature | Maleimidopropionic acid (DAC) — albumin-conjugation moiety | Includes non-natural Aib and 2-naphthylalanine residues |
| Sensitive to | Hydrolysis above pH 7.5 (maleimide ring opens) | Standard peptide degradation; relatively robust |
When researchers choose each
CJC-1295 (DAC) is the longer, albumin-conjugating reference component for studies involving in-vitro half-life extension chemistry. Ipamorelin is the short pentapeptide reference for ligand-binding studies on GH secretagogue receptors. The blend pairs them for protocols requiring co-presence; individual single-component reference standards are available on request for institutional buyers.
