Most suppliers ask you to trust a claim. We ask you to read the data. Every lot of every compound passes seven independent analytical checkpoints before it earns a label — and the results travel with the vial on a lot-matched Certificate of Analysis.
Each layer catches a different way a research compound can fail. A vial only ships once it clears all seven.
Identity Confirmation
Mass SpectrometryHigh-resolution mass spec confirms the molecular weight matches the target peptide exactly — proving the vial contains the compound on the label, not a lookalike.
Why it matters — If the identity is wrong, every downstream result is wrong. This is the first thing that must be true.
Purity Analysis
HPLCReverse-phase HPLC quantifies purity to ≥99% and resolves related-substance impurities, truncated sequences, and process residues.
Why it matters — Impurities introduce uncontrolled variables. ≥99% purity keeps your experiment measuring the compound — not the contamination.
Net Peptide Content
QuantitationContent analysis verifies the vial actually holds the stated amount of active peptide, correcting for water and counter-ion mass.
Why it matters — Accurate mass in = accurate concentration math out. No silent shortfalls between lots.
Endotoxin Screening
LAL AssayThe Limulus Amebocyte Lysate (LAL) assay screens for bacterial endotoxins down to trace levels.
Why it matters — Endotoxins skew cell-based and in-vitro assays. Screening them out protects the integrity of sensitive research models.
Sterility Testing
MicrobialEach lot is tested to confirm the lyophilized product is free of microbial contamination before it is sealed and released.
Why it matters — Contamination ruins samples and wastes weeks of work. Sterile in, reliable out.
Heavy Metals Testing
ICP-MSInductively coupled plasma mass spectrometry screens every lot for heavy-metal contaminants — lead, mercury, arsenic, and cadmium — down to parts-per-billion levels.
Why it matters — Trace metals catalyze degradation and confound sensitive assays. Verifying they're absent protects both the compound and the data it produces.
Independent Verification
Third-Party COAAn independent third-party lab confirms the analytical results, and every single lot ships with a lot-matched Certificate of Analysis you can match to the number on your vial.
Why it matters — Anyone can claim quality. We publish the proof — the data travels with the vial, verifiable before you ever open it.
Bad inputs don't just waste money — they waste months.
