What every lot is tested for

Seven analytical parameters, every lot, no exceptions, no spot checks.

• Identity, by mass

  Method: High-resolution mass spectrometry (ESI / time-of-flight)

  Proves the vial holds the exact chemical sequence on the label, not a different or mislabeled one.

• Purity, by HPLC area percent

  Method: Reversed-phase HPLC, UV detection at 210 to 220 nm

  Of everything the detector sees, what fraction is the chemical sequence you ordered versus look-alike by-products of making it.

• Sterility

  Method: Compendial 14-day culture (USP 71), membrane filtration

  Confirms nothing living grows out of the material, so the vial is not a hidden culture of bacteria or fungi.

• Bacterial endotoxins, by LAL

  Method: Kinetic chromogenic LAL (USP 85)

  Checks for traces of dead gram-negative bacterial debris, a heat-stable immune trigger that can light up assays all by itself.

• Heavy metals, by ICP-MS

  Method: Inductively coupled plasma mass spectrometry

  Measures toxic metals (lead, arsenic, cadmium, mercury) and leftover catalyst (palladium) down to parts per billion.

• Residual solvents, by headspace GC

  Method: Headspace gas chromatography (USP 467, ICH Q3C)

  Finds leftover manufacturing solvents (acetonitrile, dichloromethane, TFA) that are toxic, can interfere with assays, and are dead weight, not chemical sequence.

• Net content, by mass

  Method: Gravimetric fill on a calibrated microbalance (USP 697 / 755)

  The actual weighed mass of chemical sequence in the vial, the number you divide your volume into to get the real concentration.

Record and verification details

The released certificate identifies the method, record reference, and sale window for a lot without exposing a public lot list.

Recalls

If a lot needs to be pulled, we recall proactively by sale window, the interval between a lot's synthesis and expiry dates, so affected orders are identified automatically.
