Analyst Comments
Clear, colorless aqueous solution. Preservative identity confirmed against a reference standard. Measured benzyl alcohol content is 1.55% w/v, above the 0.9% w/v typical of commercial bacteriostatic water, consistent with evaporative loss of water from an aged or repeatedly accessed vial. This level remains well below concentrations of toxicological concern. No additional peaks greater than 1% of total area were detected. Purity is not reported for this sample type.
