Bacteriostatic water offers several advantages over alternatives: pH range of 5.0-7.0 prevents acid- or base-catalysed hydrolysis Benzyl alcohol at 0.9% concentration inhibits bacterial growth without denaturing peptides Multi-dose vials remain stable for 28 days under refrigeration (2-8C) No ionic species that could interfere with downstream analytical techniques (HPLC, mass spectrometry) Some UK suppliers provide pre-mixed solutions, but these introduce variables that complicate dose precision
