Analytical release — preparative fraction screening before pooling
Gloved analyst holding a sample vial beside a liquid chromatography instrument loaded with a sample tray

Released with evidence, not assurances.

A purity figure on its own tells a buyer very little. Each batch therefore ships as a small dossier: what was measured, on which instrument, against which specification, and who signed it off.

  • 01
    IdentityMass confirmation by mass spectrometry against the theoretical mass written into the specification.
  • 02
    PurityA chromatogram at the stated wavelength, with integration and the release threshold printed beside it — not a purity figure quoted on its own.
  • 03
    AppearanceLyophilisate or solution described as observed and photographed; anything outside the agreed description is flagged rather than reworded.
  • 04
    Moisture and fillResidual moisture and fill weight recorded for every freeze-dried presentation.
  • 05
    TraceabilityBatch number, date of manufacture, specification version and analyst signature appear on each page of the record.

Who we supply, and what we decline

The size of the order does not decide whether an enquiry proceeds. The specification, the destination and the end use do.

Who we supply

Research groups and individual researchers, distributors, permitted compounding operations where the compound is permitted, and contract research, diagnostic and academic laboratories. The same specification, documentation and published prices apply to every order.

What we do not do

No dosing, administration or therapeutic-use guidance. No representation that any material here is approved for human or veterinary use. Marketing claims are not part of the service.

Where responsibility sits

Import licensing, marketing authorisation and end-use compliance belong to the buyer. Where a destination or an end use is not lawful, we decline the order and record the reason in writing.
