Hospira Bacteriostatic Water

Sterile water for injection containing 0.9% benzyl alcohol as a preservative, manufactured by Hospira (a Pfizer subsidiary) at FDA-registered cGMP facilities. Sold by peptide vendors as a pharma-grade alternative to generic in-house bacteriostatic water for reconstituting lyophilized peptides. Chemically equivalent to USP-grade bacteriostatic water but commands a price premium for the manufacturer's assured benzyl alcohol concentration and quality control. Vendors typically sell it in 30 mL multi-dose vials.
