The Vialz Standard
Quality & testing
Purity isn't a marketing line — it's a number we publish. Here's exactly how every batch is verified before it reaches your lab.
≥99%
HPLC purity specification
100%
Batches mass-spec verified
Per-lot
Certificate of analysis
From synthesis to shipment
01
Sourcing
Compounds are synthesized to specification by audited manufacturing partners and received under chain-of-custody.
02
Identity
Mass spectrometry confirms the molecular weight and identity of every incoming lot before it is accepted.
03
Purity
Reverse-phase HPLC quantifies purity to a ≥99% specification, with the full chromatogram retained on file.
04
Fill & finish
Material is lyophilized and filled into sterile vials in a controlled environment, then sealed and labeled by lot.
05
Documentation
Each lot is assigned a batch number that maps to a downloadable certificate of analysis.
06
Cold storage
Finished vials are held desiccated and dispatched cold-chain within 48 hours of order.
Analytical Methods
What we test, and how.
- RP-HPLC — reverse-phase high-performance liquid chromatography quantifies purity and detects related-substance impurities.
- Mass spectrometry — confirms molecular weight and verifies the compound's identity against its theoretical mass.
- Appearance & fill — visual inspection of the lyophilized cake, seal integrity, and label accuracy on every vial.
