Analytical Verification & Documentation
Every compound shipped by Molecule Frontier includes a Certificate of Analysis (COA) documenting purity, identity, and batch-specific data. Our analytical standards are designed to meet the expectations of academic and institutional research environments.
Certificate of Analysis (COA)
Each COA is batch-specific and includes purity percentage, analytical method used, molecular weight confirmation, appearance, and storage recommendations. Batch-specific documentation is provided with every order and available directly on the product page.
Independent Verification
Tested by US-based analytical labs
Fully Transparent

Batch-Specific
Unique to each production lot
Analytical Methods
HPLC
High-Performance Liquid Chromatography
Primary method for peptide purity determination. Separates compounds based on molecular interaction with a stationary phase to quantify purity percentage.
QNMR
Quantitative Nuclear Magnetic Resonance
Used for small molecule purity quantification. Provides absolute purity values without reference standards by analyzing nuclear spin properties.
LC-MS
Liquid Chromatography–Mass Spectrometry
Confirms molecular identity and detects impurities. Combines chromatographic separation with mass-based detection for definitive compound identification.
Purity Standards
Peptides
Typical purity >99% by HPLC. Identity confirmed by LC-MS. TFA or acetate salt forms specified per product.
Small Molecules
Typical purity >99% by QNMR or HPLC. Structure confirmed by NMR and/or LC-MS. Solubility and storage conditions documented.
