Basic Properties & Purity Profile
The peptide is supplied as a lyophilized white powder with a purity level exceeding 98% as determined by HPLC analysis. Each batch is tested for residual solvents, heavy metals, and microbial contamination to ensure compliance with cosmetic-grade specifications. The molecular weight is verified via mass spectrometry, and the compound demonstrates excellent solubility in water and phosphate-buffered saline at concentrations up to 10 mg/mL.
- Purity: ≥98% by HPLC, with individual impurity limits below 0.5%
- Solubility: Fully soluble in water, PBS, and ethanol-water mixtures
- Stability: Lyophilized form stable for 24 months at -20°C; reconstituted solution stable for 7 days at 2-8°C
- Appearance: White to off-white lyophilized powder, free from visible particulates
- Counterion Content: Trifluoroacetate content ≤5% by weight
Industry data from the International Peptide Society indicates that peptide raw materials with purity above 98% and controlled counterion levels reduce formulation variability by up to 40% compared to lower-grade alternatives. This directly impacts batch reproducibility in commercial cosmetic production.
Manufacturing & Quality Control
The production of Kate Farms Peptide 1.5 follows a fully documented solid-phase peptide synthesis (SPPS) process using Fmoc chemistry. Each synthesis cycle is monitored by real-time conductivity and UV absorbance to ensure coupling efficiency exceeds 99.5%. After cleavage and deprotection, the crude peptide undergoes preparative HPLC purification using a C18 column with a gradient elution system.
Purification & Third-Party Testing
Following purification, the peptide is lyophilized under controlled conditions to maintain structural integrity. Every batch is subjected to a comprehensive quality control panel that includes HPLC purity analysis, mass spectrometry confirmation, amino acid analysis, and residual solvent testing by GC. Third-party certificates of analysis are provided with each shipment, and independent laboratory verification is available upon request.

Bulk Purchase Selection Guide
When sourcing Kate Farms Peptide 1.5 in bulk, buyers must evaluate several critical factors to ensure product quality and supply chain reliability. Common pitfalls include accepting certificates of analysis without independent verification, overlooking storage condition requirements, and failing to confirm batch traceability documentation.
Selection Standards for Laboratories
Laboratories should request a sample batch for in-house testing before committing to large orders. Verify that the HPLC chromatogram matches the reference standard and confirm that the peptide's solubility profile aligns with your formulation requirements. Always check that the product is shipped with cold chain packaging if ambient temperatures exceed 25°C during transit.
- Request a pre-shipment sample for independent purity verification
- Confirm storage conditions at -20°C for long-term stability
- Verify batch numbers match documentation from manufacturer to distributor
- Check lead times for bulk orders to avoid production delays
- Review return policies for temperature-damaged shipments
