Testing Methodology
Two-Method
Verification
Relying on a single analytical method leaves room for error. We require both HPLC and mass spectrometry on every batch — two independent techniques that cross-validate identity, purity, and molecular weight simultaneously.
High-Performance Liquid Chromatography (HPLC)
Separates and quantifies each component in the sample. Provides precise purity percentage by comparing peak areas. Any impurities above 0.1% are detected and reported.
Mass Spectrometry (MS)
Confirms molecular identity by measuring the exact mass-to-charge ratio of the compound. Verifies the correct peptide sequence and detects any structural anomalies or substitutions.
Residual Solvent Analysis
GC-MS screening for residual solvents from the synthesis process. All compounds meet ICH Q3C guidelines for permitted daily exposure limits.

Certificate of Analysis
What a COA Contains
A Certificate of Analysis is a formal document issued by an accredited laboratory confirming the identity, purity, and quality of a compound. Every batch we supply has one.
Compound Identity
Confirmed by mass spectrometry. Molecular formula, exact mass, and isotope pattern all verified against reference standards.
Purity Percentage
HPLC chromatogram with peak area integration. All impurities listed individually if above the 0.1% reporting threshold.
Molecular Weight
Measured molecular weight compared to theoretical value. Deviations greater than 0.01 Da trigger batch rejection.
Batch Number
Unique batch identifier traceable to synthesis date, raw materials, and testing records. Enables full supply chain traceability.
Testing Laboratory
Name, accreditation number, and ISO/IEC 17025 certification details of the independent laboratory that conducted analysis.
Residual Solvents
GC-MS screening results for common synthesis solvents. All values reported against ICH Q3C Class 1, 2, and 3 limits.
