? Sterile Water for Injection (WFI) – Research-Grade Solvent for Pyrogen-Free Reconstitution
Synonyms: SWFI, Sterile WFI
CAS Number: 7732-18-5
Form: Clear, sterile, non-pyrogenic aqueous solution
pH Range: 5.0–7.0
Use: For laboratory research only. Not for human or veterinary use.
? Overview
Sterile Water for Injection (WFI) is a high-purity, preservative-free solvent used in laboratory settings for the reconstitution of lyophilized peptides, biologics, and injectable research compounds.
Manufactured to meet USP, EP, and JP pharmacopoeia standards, WFI is free from endotoxins, microbial contaminants, and particulates. Its neutral pH and non-reactive profile make it suitable for sensitive compounds in sterile, single-use research environments.
⚙️ Functional Role in Research
Sterile WFI is commonly used in:
• Peptide Reconstitution – Suitable for compounds requiring preservative-free, neutral-pH solvents
• Single-Use Protocols – Ideal for sterile, one-time reconstitution workflows
• Carrier for Dilution – Used in formulation of injectable research compounds and biologics
• Final Rinse Applications – Supports sterile equipment preparation and vial conditioning
These roles are limited to laboratory research and are not indicative of clinical or therapeutic use.
? Research Context
Sterile WFI is being evaluated in controlled laboratory environments for its relevance to:
• Peptide and protein reconstitution
• Cell culture and biologic formulation
• Vaccine and mRNA research
• Analytical chemistry workflows requiring pyrogen-free solvents
Its preservative-free profile makes it compatible with sensitive peptides such as IGF-1 variants, GHK-Cu, and neuropeptides.
? Packaging & Storage
• Supplied in single-use sterile vials or ampoules
• Store at 20–25°C, protected from light and contamination
• Use immediately after opening to maintain sterility
• Do not reuse or store after puncture
Note: Solvent compatibility and formulation protocols are available upon request for qualified research institutions
