It is the standard reconstitution vehicle for lyophilised research peptides and proteins, allowing multiple-use vials to remain sterile over extended periods. Unlike standard sterile water, the benzyl alcohol content inhibits bacterial growth, making BWFI suitable for repeated needle entry without contamination risk.\u003c\/p\u003e\u003ch3\u003eResearch Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eReconstitution of lyophilised research peptides and proteins\u003c\/li\u003e\n\u003cli\u003ePreparation of multi-use peptide stock solutions\u003c\/li\u003e\n\u003cli\u003eVehicle control in in vitro and in vivo research protocols\u003c\/li\u003e\n\u003cli\u003eStability and solubility studies for injectable research compounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eUsage Notes\u003c\/h3\u003e\u003cp\u003eBacteriostatic Water is the preferred reconstitution solvent for most research peptides including GH-releasing peptides, GLP-1 analogues, and growth factors. For peptides with poor aqueous solubility, initial dissolution in 1% acetic acid followed by dilution with bacteriostatic water is recommended. Reconstituted solutions should be stored at 4°C and used within 28 days.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposition:\u003c\/strong\u003e Water for injection + 0.9% benzyl alcohol (preservative)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular Formula (water):\u003c\/strong\u003e H₂O\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular Weight (water):\u003c\/strong\u003e 18.02 g\/mol\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCAS Number (water):\u003c\/strong\u003e 7732-18-5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade:\u003c\/strong\u003e USP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e Sterile aqueous solution\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage:\u003c\/strong\u003e 4°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShelf Life:\u003c\/strong\u003e 24 months\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eThis product is intended for legitimate laboratory and analytical research use only.
