Analytical methods

What every batch is tested for

Each lot is submitted to an independent laboratory and analyzed against documented USP method specifications. Results are recorded on a per-lot Certificate of Analysis.

USP <621>

HPLC purity

High-performance liquid chromatography quantifies peptide purity against a ≥98% acceptance specification for each lot.

USP <197A>

FTIR identity

Fourier-transform infrared spectroscopy confirms the characteristic bands of the labeled compound for identity verification.

USP <621>

Potency assay

Labeled content is measured by assay and reported on the certificate alongside the recorded mass for the lot.

Transparency

Current batch results

HPLC purity figures below are taken directly from the third-party Certificate of Analysis issued for each current lot. Full certificates — including chromatograms and potency data — are available per product.

Research standards

How material is handled

Lyophilized & sealed

Material is supplied lyophilized in sealed glass vials, prepared and stored to protect compound integrity during handling and transit.

Per-lot documentation

Each lot carries its own Certificate of Analysis with a unique lot number, making every batch independently traceable to its analytical record.

Independent verification

Analysis is performed by a third-party laboratory rather than in-house, so purity and identity figures come from an external source.

Documented dispatch

Orders are prepared in protective packaging with tracking, and shipped to the verified researcher or institution on the account.

Questions

Documentation & ordering

What is included with each compound?+
Every lot is supplied with access to its third-party Certificate of Analysis, listing identity confirmation, HPLC purity, potency assay, and the unique lot number for that batch.
Who performs the testing?+
Analysis is performed by BTLabs, an independent third-party analytical laboratory in West Palm Beach, FL, with no affiliation to RNXResearch. Certificates are issued directly under their report numbers.
What does the Certificate of Analysis confirm?+
