TB-500 is a good example of why naming and batch traceability matter in research-material documentation. Product naming can be used differently across catalogues, so the label, sample reference and analytical record should be reviewed together rather than relying on a familiar product name alone.
Resolve naming before comparing reports
Record exactly how the supplier identifies the material: product title, catalogue reference, sample code and any sequence or specification information that is provided. When two documents use different names or abbreviations, confirm that they refer to the same intended research material before comparing results.
Connect the report to the batch
A batch-specific report should carry an identifier that matches the material supplied. If a certificate has no batch, lot or sample reference, it is difficult to demonstrate that it belongs to a particular vial or shipment. Keep representative supplier reports separate from current-lot documentation.
Do not collapse identity and purity
Purity data can describe the relative amount of a principal component under a stated analytical method. It does not automatically establish identity. For procurement review, record identity-related data and purity-related data as separate fields and note which analytical method produced each result.
Core verification fields
- Material name and catalogue reference.
- Batch, lot or sample code.
- Analytical method.
- Analysis date.
- Laboratory or issuing entity.
- Reported result and units.
- Report number.
- Verification link or QR destination where available.
Build a clean audit trail
For each lot, store the label image, batch number, order record and analytical documentation as one set. If new testing is performed, add it to that set rather than replacing prior reports. The result is a more useful history for cross-batch comparison and supplier qualification.

FAQ
Why is consistent naming especially important?
Because catalogue names, abbreviations and sample codes can vary. Consistency makes it easier to demonstrate that the document refers to the intended material.
Can an older supplier COA be useful?
Yes, as a historical or representative reference, but it should not be presented as current-batch evidence when the lot does not match.
What should be archived for each lot?
At minimum, the label or package identifier, batch code, purchase record and associated analytical documentation.
