As demand surges for bioactive peptides that stimulate collagen synthesis and support skin repair, Prezatide copper acetate has emerged as a scientifically validated alternative to traditional copper-peptide complexes. With the CAS number 130120-57-9, this compound—chemically defined as (2S)-6-amino-2-[[(2S)-2-[(2-aminoacetyl)amino]-3-(1H-imidazol-5-yl)propanoyl]amino]hexanoic acid complexed with copper and acetic acid—is prized for its stability, water solubility, and multifunctional efficacy in sensitive-skin formulations. When sourcing high-purity Prezatide Copper Acetate, buyers must prioritize suppliers who provide transparent Certificates of Analysis (COA) and detailed specification sheets aligned with international cosmetic regulations.
Understanding the Certificate of Analysis (COA) for Prezatide Copper Acetate
A robust COA is non-negotiable for B2B buyers evaluating peptide actives. For Prezatide copper acetate—a GHK-Cu derivative engineered for enhanced performance—the COA should include the following key analytical parameters:
- Assay (Purity by HPLC): Typically ≥98.0%, confirming the active content meets formulation requirements.
- Water Content (KF): ≤6.0%, critical for stability in aqueous systems.
- Residual Solvents (GC): Must comply with ICH Q3C guidelines (e.g., methanol < 3000 ppm, acetone < 5000 ppm).
- Heavy Metals (ICP-MS): Total heavy metals ≤10 ppm, with lead ≤2 ppm and arsenic ≤1 ppm.
- Microbial Limits: Aerobic count ≤100 CFU/g; absence of E. coli, S. aureus, and C. albicans.
These benchmarks ensure the material is suitable not only for cosmetic use but also for applications requiring pharmaceutical-grade rigor, such as post-procedure skincare or barrier-repair serums.
Specification Sheet: Technical Profile and Formulation Compatibility
The molecular formula of Prezatide copper acetate is C32H54CuN12O12, with a molecular weight of 862.39 g/mol. It appears as a deep blue powder and exhibits excellent solubility in water (<5% w/v at 25°C), enabling direct incorporation into the water phase of emulsions below 40°C. This thermal sensitivity necessitates addition during the cool-down phase of manufacturing to preserve bioactivity.
As a functional copper tripeptide-1 analog, it delivers anti-inflammatory, wound-healing, and extracellular matrix remodeling effects—making it ideal for “antisensitive repair” claims in modern skincare. Its mechanism involves upregulating collagen I, III, and elastin while modulating MMP activity, offering a compelling performance benchmark against legacy peptides.

Drop-in Replacement Strategy and Bulk Sourcing Advantages
Formulators seeking cost-effective yet high-efficacy alternatives are increasingly adopting Prezatide copper acetate as a drop-in replacement for other copper-peptide complexes. Its structural similarity to GHK-Cu—but with dual lysine-histidine-glycine motifs—enhances receptor affinity and prolongs dermal residence time. This makes it particularly valuable in premium anti-aging essences, calming masks, and sun care products targeting inflammation-driven photoaging.
For brands scaling production, securing a reliable source of consistent, high-purity material is paramount. NINGBO INNO PHARMCHEM CO.,LTD. stands out as a leading global manufacturer of Prezatide copper acetate, offering full traceability, GMP-aligned production, and comprehensive technical dossiers—including COA, SDS, and formulation guide support. Their batches undergo rigorous QC to ensure batch-to-batch consistency, a critical factor for regulatory compliance in EU, ASEAN, and North American markets.
Moreover, as a direct producer (not a trader), NINGBO INNO PHARMCHEM CO.,LTD. provides competitive bulk price structures without compromising on documentation quality—enabling brands to validate claims with confidence while optimizing COGS.
