Benzyl Alcohol 0.9%

Benzyl Alcohol

Benzyl Alcohol 0.9% Solution constitutes a pyrogen-free, sterile aqueous medium featuring benzyl alcohol at 0.9% (v/v) within ultra-pure water, engineered for research-grade biological reagent preparation applications. This formulation acts as a dilution agent, preservative-fortified medium, or carrier in experimental workflows demanding solvent consistency and bacterial inhibition.

In laboratory research contexts, this solution finds application in peptide dilution operations, reusable reagent container preparation, lipophilic substance dissolution, and as a sterile medium for analytical or cellular assay procedures. The benzyl alcohol component confers antimicrobial preservation properties, while the ultra-pure water matrix provides minimal interference with subsequent analytical processes.
