Certificate of Analysis Library

The MOG Research Certificate of Analysis Library is the searchable archive of batch-specific testing documentation for every research peptide we have shipped. Each COA includes HPLC purity chromatogram, mass spectrometry identity trace, and LAL endotoxin assay result for the corresponding lot.

Browse by Lot Number

Locate the lot number printed on your vial label, then enter it below to retrieve the corresponding Certificate of Analysis. Lot search launches with the next batch upload — in the meantime, request a COA by emailing office@mogresearch.com with your lot number and order reference.

What a COA Documents

• HPLC Purity Chromatogram — full trace showing target peptide peak and any secondary peaks, with the calculated ≥99% purity result
• Mass Spectrometry Identity — ESI-MS trace confirming the detected molecular weight matches theoretical MW within tolerance
• LAL Endotoxin Assay — quantified result in EU/mg with pass/fail designation against the <1 EU/mg research-grade threshold
• Batch Metadata — lot number, manufacturing date, testing date, testing facility name and signature, storage and handling recommendations

For a complete breakdown of how to read each section of a COA, see How to Read a Peptide Certificate of Analysis.

Why COAs Matter

A research peptide CoA serves three functions in a laboratory context. First, it confirms the material in your vial is the compound named on the label, with the purity required for the planned experiment. Second, it provides the supplier-side characterization data that peer-reviewed publications often request when material is reported in methods sections. Third, it enables traceability — if a batch is later found to have manufacturing issues, lot-level documentation lets researchers identify affected experiments and assess impact.

For the full quality framework that produces these COAs, see Research Peptide Quality Standards.

Historical Lot Archive

MOG Research maintains COA documentation indefinitely. Past batches do not roll off the archive when new batches ship — researchers can retrieve documentation for any compound and lot we have ever shipped. This is intentional: experimental work conducted with a 2024 batch may be revisited or published in 2027, and the supporting COA needs to remain accessible without contacting customer support.

For research use only. Not for human or animal consumption.
