Five procurement classifications
Navigate the catalog by reagent classification. Each classification carries its own release criteria, documentation set, and transport protocol.
Analytical verification before any lot is released
No reagent leaves the facility without a completed dual-method assay package, documented water and residual-solvent analysis, and a lot-specific Certificate of Analysis signed by the releasing analyst.
C18, 0.1% TFA / acetonitrile gradient, 214 nm. Main peak integration 99.2% area.
-
01
Reverse-Phase HPLC
Gradient elution on a C18 stationary phase with UV detection at 214 nm establishes chromatographic purity and resolves process-related impurities.
-
02
ESI Mass Spectrometry
Electrospray ionisation confirms molecular identity against the theoretical monoisotopic mass within a 0.1% tolerance window.
-
03
Water & Residual Solvent
Karl Fischer titration and headspace gas chromatography document water content and residual synthesis solvents per lot.
-
04
Batch Traceability
Every vial is indexed to its synthesis campaign, purification run, fill record, and released Certificate of Analysis.
