The Manufacturing Process
From raw amino acids to certified research compound — every step under Swiss pharmaceutical-grade control.
Amino Acid Synthesis
Proprietary production of ultrapure building blocks in-house — no third-party sourcing.
Peptide Assembly
Solid-phase and solution-phase synthesis under strictly controlled clean-room environments.
HPLC Purification
Chromatographic purification removes impurities to achieve ≥99.97% purity levels.
Lyophilization
Freeze-drying preserves peptide stability for long-term storage and transport integrity.
Analytical QC
HPLC, MS, LAL endotoxin, amino acid analysis — every batch independently verified.
COA Issuance
Certificate of Analysis documenting all test results issued for every production batch.
Certificate of Analysis Specifications
Every batch of every compound in The Egyptian Collection is tested against the following specifications. Certificates of Analysis are available for download on each product page.
Testing Methodology
HPLC Analysis
High-Performance Liquid Chromatography separates, identifies, and quantifies each component in a peptide sample using C18 reverse-phase columns. Our ≥99.97% purity threshold means that ≥99.97% of the measured compound is the intended molecule, with ≤0.03% impurities. This exceeds industry-standard thresholds by a significant margin.
Mass Spectrometry (ESI-MS)
Electrospray Ionization Mass Spectrometry confirms the molecular weight and identity of each peptide with precision of ±0.1 Daltons. This ensures the compound matches its intended amino acid sequence and structure — providing definitive identification beyond chromatographic purity alone.
Endotoxin Testing (LAL)
Limulus Amebocyte Lysate testing using kinetic turbidimetric methodology confirms endotoxin levels below 0.25 EU/mg — classified as endotoxin-free under USP <85> guidelines. This is critical for research applications requiring sterile-grade compounds free of bacterial contamination.
Residual Solvent Analysis
Gas Chromatography headspace analysis screens for residual manufacturing solvents. All compounds meet ICH Q3C(R8) guidelines for residual solvents in pharmaceutical products, ensuring no harmful solvent residues remain after the purification and lyophilization process.
How to Read a Certificate of Analysis
Product Identification
The top section identifies the compound by name, molecular formula, molecular weight, catalog number, and batch/lot number. This is your reference for matching the COA to the specific vial you received.
Purity & Identity Results
The core of the COA. Look for the HPLC purity percentage (should read ≥99.97%) and the MS identity confirmation (confirmed molecular weight matching the target compound). These two results together verify both purity and identity.
Safety Parameters
Endotoxin level (LAL test result, reported in EU/mg), residual solvents (ICH Q3C compliance), and water content (Karl Fischer %). These parameters confirm the compound is safe for laboratory research use and free of manufacturing contaminants.
Dates & Signatures
Every COA includes the manufacture date, test date, and expiry/retest date. The document is reviewed and signed by the Quality Control department of the manufacturing facility. These dates are critical for ensuring compound integrity within the stated shelf life.
COA documents are available for download on each product page. For batch-specific requests, contact support@sphinxpeptides.com with your order number and batch number.
