Summary
When a peptide certificate of analysis PDF arrives at lab receiving, file-hygiene practice is to name and store the file from printed strings on that report after a lot + name + strength match — not from memory, a catalog page, or another lot. A tidy filename is not a substitute for reading the COA field-by-field (How to Read a Peptide Certificate of Analysis), matching the vial lot (Matching Lot Numbers: From Vial Label to the COA Library), or confirming strength (Lot-Specific COA: Why Strength and Catalog Name Are Not Enough). This article covers documentation literacy for organizing COA PDFs — not inventing identifiers, not purity claims, and not use protocols.
Why filename hygiene matters (and what it is not)
| Practice | Job | What it is not |
|---|---|---|
| Filename from printed lot + product (+ strength / test date when printed) | Makes the matching PDF findable later | Not a purity, identity, or “third-party” claim |
| Folder / library path that mirrors lot filing | Keeps receiving and inventory notes aligned | Not permission to invent a lot ID when the PDF lot is blank |
| Keeping the original vendor filename as a sidecar note | Preserves provenance | Not a substitute for lot match before filing fields |
A filename that looks complete does not authorize filling blank COA cells. Blank fields still follow document-or-delete rules on Academy 12.
A conservative naming pattern (literacy only)
Use only strings printed on the matching certificate (and/or the vial label after a three-way match). A common, readable pattern:
ProductName_Strength_Lot_TestDate_Lab.pdf
Rules:
- Product name — copy the report’s product / catalog name string as printed (normalize spaces to underscores if needed; do not “correct” to a different SKU name).
- Strength — include only if printed and if it matches the vial / live SKU strength (Academy 14).
- Lot — copy the printed lot exactly; do not invent a lot ID if the field is blank or “Unknown.”
- Test / analysis date — include only if printed; copy into notes per Academy 16; do not invent a date for the filename.
- Lab — include the named lab string only if printed on that report; never invent a lab name to support “third-party tested.”
If a field is blank on the PDF, omit that segment from the filename rather than guessing.
Receiving checklist (before renaming)
- Open the PDF; confirm it is a certificate of analysis (not a packing slip or generic catalog sheet).
- Match lot on PDF to vial / library row (Academy 09).
- Confirm product name + strength (Academy 14).
- List printed fields; leave blanks for missing ones.
- Rename using only printed segments.
- Store beside inventory notes that cite the same lot — still do not invent purity, method, CAS, or identity for blank cells.
Patterns that fail file hygiene
| Situation | Inventory action |
|---|---|
| Lot blank / “Unknown” on PDF | Do not invent a lot for the filename; keep vendor original name; omit complete-row claims |
| Strength on PDF ≠ vial | Do not file or rename as if it documents the vial lot (Academy 14) |
| Another lot’s PDF for same catalog name | Different lot — different file; do not overwrite or merge |
| Filename includes purity % you typed from memory | Remove invented purity; purity belongs only if printed on the matching report |
| Renamed before lot match | Stop; match first, then rename |
How this ties to test-date and lot notes
If the report prints a test / analysis date, copy that date into inventory notes (Academy 16) and optionally into the filename segment — still without treating it as expiry unless expiry language is separately printed. Lot filing still starts with vial → library match (Academy 09).
