No chromatogram is issued for this line. It is a reconstitution diluent rather than a peptide, and it releases on sterility, endotoxin and container-closure integrity — the panel below is the whole record.

This line releases on sterility, endotoxin and container closure rather than an area-purity figure — there is no peptide to chromatograph. The rule reads full because every release test conformed.

TEST	RESULT, THIS LOT
Benzyl alcohol (GC)	0.91% w/v
Sterility (USP <71>)	Pass — 14-day incubation
Bacterial endotoxin	< 0.06 EU/mL (LAL)

This is the sheet for the lot on the shelf — not a representative document. If the lot number moves on before you order, the page moves with it.

Handling

Swab the septum before every entry; the bacteriostat is not a substitute for technique.
Benzyl alcohol absorbs at 214 nm — expect it in the void volume of any trace you run.
Do not use as a diluent where the bacteriostat would interfere with the assay.

For laboratory research use only.
