03 · Quality
Every batch is tested at an accredited independent laboratory. We publish the full HPLC chromatogram and mass-spectrometry report for the exact lot you receive, available by scanning the vial.
Sample a COA →Purity floor audited per lot; specimens below threshold are destroyed, not downgraded.
Janoshik Analytical, ACS Labs, and NovaBioAssay. Results published per lot.
Orders route through EU fulfillment with lot documentation retained for every release.
Each vial carries a unique identifier bound to synthesis, purification, and verification records.

04 · Process
Solid-phase Fmoc synthesis in class-100 cleanroom conditions. Amino acid provenance is logged per sequence.
Preparative reverse-phase HPLC with gradient elution. Target fractions collected at >99% UV-area.
MS/MS confirmation of target mass, endotoxin screening, and independent purity audit before release.
Alvar was built for researchers who read the underlying report, not just the headline purity number. Every lot is reviewed against the full assay record, published with its supporting documentation, and rejected when it does not meet spec.
05 · Coverage
Distribution is focused on EU research accounts, coordinated from Rotterdam with documented lot release records.
