Our framework is designed to support supplier evaluation, batch-level records, and analytical documentation when verified records are available for a material.
We keep a clear line between how we work, what has been verified, and what is listed for reference.
How we approach supplier evaluation, records, and analytical documentation across the catalogue.
Records tied to a specific batch, published only when they are available for a material.
Listings that provide reference information and do not yet carry verified batch documentation.
Each stage is designed to produce records that stay attached to a material, so documentation can be surfaced when it is available.
Suppliers and materials are evaluated as part of onboarding a listing.
Incoming materials are logged and checked against records.
The framework is designed to record material identity for listed materials.
Analytical review is documented where verified records exist.
Findings are documented against the analytical method used.
Documentation is organized against a batch reference.
Storage guidance is captured alongside verified records.
Records are retained and linked to their batch.
Recording that a material is consistent with its reference characteristics, where verified records exist.
Reviewing purity against a named analytical method, reported alongside the conditions of measurement, when records are available.
Mass-based evidence that can contribute to identity and molecular-weight confirmation, where applicable.
Chromatographic review that can support the reported proportion of a target compound.
Linking documentation to a batch reference that can be cited later.
Storage and handling guidance provided alongside verified batch records.
Batch-specific documentation will be published only when verified records are available for a listed material. When those records exist, they are provided on request through our documentation inquiry process.
