Our materials are backed by batch-specific Certificates of Analysis from independent third-party HPLC testing.
Research integrity depends on compound purity. We verify every batch so you can trust your results.
Every batch is tested by an independent analytical laboratory — never in-house only. This eliminates conflicts of interest and ensures objective purity verification.
Purity is determined by high-performance liquid chromatography (HPLC), the standard method for quantifying the target compound in a sample. Results are reported on each batch-specific Certificate of Analysis.
We hold every product to a minimum purity threshold of 98% by HPLC. Batches that fall below this standard are rejected and never shipped to researchers.
From synthesis to your lab — every step is documented and verified.
Peptides are synthesized via solid-phase peptide synthesis (SPPS) and purified using preparative HPLC to remove truncated sequences and impurities.
Each batch is sent to an independent third-party laboratory for HPLC purity analysis, and the results are recorded on a batch-specific Certificate of Analysis.
A unique Certificate of Analysis is generated for each production batch, documenting purity, identity, and lot number. This COA ships with your order.
Every COA documents the analytical results for a specific production batch. Here's what each section means.
Compound name, molecular formula, molecular weight, CAS number, and batch/lot number for traceability.
The percentage of the target peptide in the sample, determined by reverse-phase HPLC. Look for ≥98% on research-grade compounds.
Molecular formula, molecular weight, and CAS number are reported so the material can be matched against reference data for the target compound.
Physical characteristics of the lyophilized powder — color, form, and reconstitution behavior in standard solvents.
Bacterial endotoxin levels (LAL test) and sterility data when applicable. Critical for in-vitro cell culture applications.
