Reconstitute with bacteriostatic water. Typical laboratory protocols use 1–2 mL per vial depending on desired concentration. For research handling only.
CAS/Ident: {{ cp.cas }} · Molar mass verified by MS · Purity ≥{{ cp.purity }} by HPLC.
Store lyophilized vials at −20°C for long-term stability. Once reconstituted, refrigerate at 2–8°C and use within the recommended window.
Discreet, temperature-controlled packaging distributed across the EU in 2–4 business days.
Peptx exists because research is only as good as its inputs. We built a supply chain where purity is proven — not promised.
Four verification gates stand between raw synthesis and the vial on your bench.
Solid-phase synthesis in audited facilities with sequence-verified starting material.
Accredited third-party labs measure purity by high-performance liquid chromatography.
Molecular mass confirmed against theoretical sequence weight for compound identity.
Lyophilized, sealed, and shipped temperature-controlled to preserve stability EU-wide.
Each lot carries a unique identifier tying it to its own Certificate of Analysis — HPLC chromatogram, mass-spec trace, and purity result for that exact batch. No generic PDFs, no shared documents.
Traceable to the exact vial on your bench.
Reports come from accredited external laboratories.
