Storage requirements mandate sealed, moisture-proof packaging at -20°C to maintain stability over 24 months. National testing standards, such as those from the Chinese Pharmacopoeia, require verification of purity, endotoxin levels, and heavy metal content.
- Purity Grade: ≥99% by HPLC, with single impurity ≤0.5%
- Endotoxin Level: ≤0.5 EU/mg, suitable for sensitive cell-based assays
- Solubility: Clear solution at 50 mg/mL in water, pH 6.0-7.5
- Storage Stability: 24 months at -20°C, 6 months at 4°C after reconstitution
- Heavy Metal Content: ≤10 ppm, compliant with ICH Q3D guidelines
According to a 2023 market analysis by Grand View Research, the global NAD+ supplement market is projected to reach $1.2 billion by 2030, driven by demand for high-purity raw materials in research and cosmetic applications, with purity standards above 99% becoming a baseline for premium sourcing.
Manufacturing Flow & Strict Quality Control System
The production of NAD+ peptide begins with raw material screening of pharmaceutical-grade precursors, followed by chemical synthesis using solid-phase or solution-phase methods. Multi-stage purification via preparative HPLC and ion-exchange chromatography ensures removal of by-products and solvents. Third-party testing certification, including cGMP compliance in ISO 9001-certified facilities, validates each batch. Long-term stability tests under accelerated conditions (40°C/75% RH for 6 months) confirm product integrity, with detailed Certificates of Analysis (CoA) provided for traceability.
