Lab Standards

When mass matches but purity fails

A batch can be unambiguously the right compound and still not be releasable. Here is how we handle it.

Two independent gates

Identity and purity are separate release gates. A batch that confirms identity but reports 97.4% purity has failed release even though the vial genuinely contains the labelled compound.

Why we do not release near-misses

Publishing a 99%+ standard and then shipping 97% material makes every other number we publish unverifiable. The threshold only has value if it is absolute.

What happens to the material

Quarantined material is recorded against its batch identifier and destroyed. It is never repackaged, discounted or blended into another run.
