What does “target purity” mean on a catalog page?

Target purity is catalog specification language for a SKU—the intended release expectation described for planning. It is not a measured result for a specific vial sitting in inventory.

Where do lot-specific purity values appear?

Measured purity belongs on the lot Certificate of Analysis and the matching Research Vault batch record when a real certificate is on file. Until then, catalog targets should not be treated as lot data.

Can I use a catalog target instead of a COA?

No. Laboratory quality systems need lot-linked documentation. If a COA is pending, that status should be labeled honestly and escalated through procurement before critical assays.

How do identity and purity differ?

Identity asks whether analytical evidence is consistent with the expected compound. Purity estimates how much of a measured signal is attributable to the primary analyte under a named method. Both may appear on a COA; neither authorizes human or veterinary use.

When does PEPerchini publish a Vault lot page?

Lot records publish only when a real Certificate of Analysis is on file—no demo certificates, invented laboratories, or fabricated analyte rows.

Quality

Quality standards for research materials

A public description of documentation expectations, batch traceability, and transparent certificate status — without fabricated accreditations.

Principles

Lot records publish only when a real Certificate of Analysis is on file—no demo certificates
Identity and purity fields are shown when data exists for that lot
Pending certificate status is labeled honestly
No fake ratings, reviews, or laboratory credentials are published

Lot traceability

When a lot is published, its identifier links to the Research Vault. Researchers can also use batch verification to open a record by lot number. Until certificates arrive, those surfaces stay in a pending state.

Target purity versus lot purity

Catalog target purity lines describe the intended release specification language for that SKU. Lot purity is the measured value reported on a batch-linked COA under a named method. Do not treat a catalog target as a substitute for the lot certificate. For method context, see purity versus identity and understanding COAs.
