Purity you can verify, not just claim.
Every lot is characterized before release and documented lot-by-lot. Here’s exactly how material is tested, what’s on a Certificate of Analysis, and the standards behind sourcing.
Four checks before a lot ships.
Identity
Compound identity is confirmed by electrospray mass spectrometry (ESI-MS) against the expected molecular weight.
Purity
Reversed-phase HPLC with UV detection quantifies purity as area %, resolving related impurities from the main peak.
Appearance & fill
Each lot is checked for appearance, fill and reconstitution behavior against the release specification.
Documentation
Results are compiled into a lot-specific Certificate of Analysis that ships with every order.
The data behind the documentation.
Release testing produces numbers, not adjectives. A snapshot of recent performance across lots.

Certificate of Analysis
What’s on every certificate.
A Certificate of Analysis is the analytical record for a specific lot. It ties the vial in your hand to the data behind it.
- Compound & lot — the exact material and batch.
- Purity & method — area % with the HPLC method and detection wavelength.
- Identity — mass-spec confirmation against expected MW.
- Retention time & appearance — chromatographic and visual checks.
Third-party testing on representative lots.
Beyond in-house release testing, representative lots are sent to independent analytical laboratories to corroborate identity and purity. These reports are available on request before you order.
- Independent HPLC purity confirmation
- Orthogonal identity confirmation by MS
- Reports retained and traceable to lot

Manufacture to dispatch
Controlled from synthesis to shipment.
Quality starts upstream of the analytics. Material is produced and handled under documented controls at every step.
Controlled synthesis
Material is produced to defined specifications with batch records that follow each lot through to release.
Intake screening
Incoming lots are checked against specification before they are accepted into inventory and listed for sale.
Cold-chain handling
Lyophilized material is stored and shipped under temperature control to preserve integrity in transit.
