Identifiers are published properties of the molecule. Values we cannot confirm are omitted rather than estimated.
Reconstitution water is sterile water containing 0.9 percent benzyl alcohol. The benzyl alcohol is a formulation excipient rather than an active ingredient, and it is what distinguishes this solvent from plain sterile water, which contains none.
Plain sterile water is the same solvent without that excipient, so the two differ in composition rather than in grade.
Benzyl alcohol is phenylmethanol, a simple aromatic primary alcohol. Labelled concentrations are 0.9 percent, that is 9 mg/mL, or 1.1 percent depending on the product, and the pH is typically around 5.7 within a range of about 4.5 to 7.0, with no buffer added.
The word bacteriostatic is a technical classification rather than a marketing term, and the distinction it draws is worth understanding. A bacteriostatic agent inhibits visible growth without necessarily killing the organism; the formal criterion compares the minimum bactericidal concentration with the minimum inhibitory concentration, and a ratio above four defines bacteriostatic behaviour. Benzyl alcohol acts on the membrane, increasing fluidity and reducing structural stability, and has also been reported to interfere with efflux pumps. Biophysical measurements on model bilayers show measurable increases in permeability and capacitance at low millimolar concentrations.
Its limits matter as much as its function. Activity is reported to be greatest below pH 5 and to fall away above pH 8, and published comparisons found greater activity against Gram-negative organisms than against Gram-positive organisms or fungi. Public health guidance is explicit that the preservative has no effect on viruses and does not provide complete protection against bacterial contamination. It inhibits growth between entries; it does not sterilise anything, and it does not rescue a vial that has been contaminated.
On storage, the manufacturer label specifies controlled room temperature, 20 to 25 degrees Celsius, rather than refrigeration.
Benzyl alcohol itself oxidises readily in the neat state, which is why bulk material is stored under nitrogen and protected from light; in the dilute aqueous form supplied here the practical requirement is simply an intact closure and storage at the labelled temperature.
Background
Reconstitution water is sterile water with benzyl alcohol added as a formulation excipient; plain sterile water is the same solvent without it, so the two differ in composition rather than in grade. Benzyl alcohol is phenylmethanol, a simple aromatic primary alcohol that acts on bacterial membranes, increasing fluidity and reducing structural stability. It is bacteriostatic in the technical sense: it inhibits visible growth without necessarily killing the organism. The solution is unbuffered, with a pH typically around 5.7.

Storage & handling
Handling notes
The manufacturer label specifies controlled room temperature, 20 to 25 degrees Celsius, rather than refrigeration.
Keep the closure intact; in this dilute aqueous form that and the labelled temperature are the practical requirements.
The preservative inhibits growth between entries but does not sterilise anything and does not rescue a vial that has been contaminated.
Benzyl alcohol has no effect on viruses, and its activity is reported to be greatest below pH 5 and to fall away above pH 8.
Safety & handling
Bench handling, not a dosing guide.
Intended use
Supplied strictly as a laboratory research material for in-vitro study by qualified researchers. Not for human or veterinary use, not for ingestion or injection, and not for any clinical or diagnostic application.
Personal protective equipment
Handle with gloves, eye protection and a laboratory coat. Weigh and transfer lyophilized powder in a ventilated enclosure to avoid generating an inhalable dust.
Reconstitution
Reconstitute against the diluent and volume appropriate to your protocol, adding solvent slowly down the vial wall rather than directly onto the pellet. Do not shake. This is a handling note, not a dosing guide.
Storage after opening
Once reconstituted, refrigerate and use within the period appropriate to the material. Avoid repeated freeze-thaw cycles, which degrade peptides faster than continuous storage at the listed temperature.
Disposal
Dispose of material and containers in accordance with your institution's chemical waste procedures and applicable local regulations.
