HPLC purity
High-performance liquid chromatography determines the share of the target peptide. The release threshold is 99 %. The chromatogram is part of the certificate, not a summary line.
Quality at SYNTEQ is a measurement, not a promise. Every batch is released only with its analytical record.

High-performance liquid chromatography determines the share of the target peptide. The release threshold is 99 %. The chromatogram is part of the certificate, not a summary line.

The measured mass is compared with the calculated mass of the sequence. A peptide that is pure but wrong is still wrong; identity is confirmed separately from purity.

Each batch ships with a CoA stating purity, identity, appearance, net content and the contaminant panel: endotoxins, residual solvents, heavy metals.

Lyophilized peptides are stable when kept cool and dry. Storage, transport and packaging are designed around that: insulated shipping, sealed vials, labels with amount and batch.

SYNTEQ material is for laboratory research. We make no statements about effects in humans and no therapeutic claims. Literature references on a data sheet are orientation for researchers, nothing more.
