Molecular formula and weight describe the substance identified by that CAS number. Confirmation that a specific batch matches this identity comes from the specification sheet and COA.
Appearance and handling
| Item | Value |
|---|---|
| Appearance | Blue to purple powder |
| Solubility | ≥ 100 mg/mL (H2O) |

Test methods are shown only where the documents we hold state them. A dash means the document does not name a method.
The molecular formula and weight shown here are the ones stated in the TDS we hold. The PubChem record for CAS 89030-95-5 describes the copper peptide complex cation as C14H23CuN6O4+ with a molecular weight of 402.92 — one hydrogen different — and that record does not include chloride. Ask us to confirm the exact figure for the salt you are buying.
These figures are the tolerances stated in the TDS and COA for this item. Ask us to confirm the specification that applies to your order.

Buying notes
We supply this material as a powder in two salt forms. The hydrochloride and the acetate carry different CAS numbers and different storage requirements, so please state which form you need.
If you are comparing copper tripeptide-1 suppliers, send us the salt form, the target specification and the quantity. GHK-Cu is another name for the same material.
