AHK-Cu Copper Peptide
AHK-Cu is a copper peptide complex formed from the tripeptide Alanine-Histidine-Lysine (AHK) and copper. It is associated with CAS No. 682809-81-0. The product is supplied as a bluish to bluish-purple powder and is easily soluble in water. The current specification includes purity of ≥98.0%, AHK peptide content of ≥65.0%, and copper content of 8.0–14.0%. Quality parameters also include solution clarity, pH, loss on drying and elemental impurities.

Description
AHK-Cu, also known as Alanine-Histidine-Lysine Copper Complex, is a copper complex of the AHK tripeptide. PubChem associates AHK-Cu with CAS No. 682809-81-0 and identifies L-Alanyl-L-histidyl-L-lysine as its parent peptide.
The product is supplied as a bluish to bluish-purple powder and is easily soluble in water. A 0.5% aqueous solution should be clear and transparent without obvious flocculent material. The pH specification at 1 mg/mL is 5.5–8.0.
Purity is specified at ≥98.0%, AHK peptide content at ≥65.0%, and copper content at 8.0–14.0%. Loss on drying and elemental impurities including lead, arsenic, cadmium and mercury are also controlled according to the current specification.
Actual batch results are provided in the corresponding Certificate of Analysis.
