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.
I started Alvar because I couldn't find a supplier I would use myself. Every order felt like a leap of faith. So we built the supplier we wanted to exist — one that publishes the full report, ships under data-logged cold-chain, and destroys anything that does not meet spec.
05 · Coverage
Two fulfillment nodes — Wilmington, DE for the Americas and Rotterdam, NL for EU, UK, and APAC — keep transit times short and temperature excursions rare.

If something isn't covered here, our research liaison team responds within one business day.
Licensed research institutions, accredited laboratories, and qualified independent researchers. Account verification is required before the first order.
Every vial includes a unique identifier and QR code. Scanning returns the exact HPLC chromatogram, mass-spectrometry report, and endotoxin screen for that specific lot.
Each shipment contains a data-logger. Any excursion outside 2–8 °C triggers an automatic replacement — you do not need to file a claim.
Yes. Bulk synthesis and custom sequences are handled through our research liaison program. Lead times from four weeks.
Synthesis is performed in the Netherlands; distribution originates from Wilmington, DE. All shipments move within certified cold-chain.
