Description

Molecular Details

• Formula: H₂O (Water)

• Contents: Sterile water for injection with 0.9% benzyl alcohol (9 mg/mL) as a preservative.

• Molecular Weight: 18.015 g/mol (for water)

Characteristics

• Bacteriostatic agent: The benzyl alcohol prevents bacterial growth in the solution.

• pH Range: Typically 4.5 – 7.0.

• Sterility: Supplied sterile and non-pyrogenic.

• Container Size: Often in 30 mL vials, intended for multiple withdrawals.

Research Applications

• Used to reconstitute lyophilized peptides, proteins, or hormones into solution.

• Allows multiple uses from the same vial due to bacteriostatic properties.

• Common in laboratory settings for preparing short-term storage peptide solutions.

• Preferred when a compound needs to be dissolved and maintained in liquid form for a few days.

Storage & Handling

• Storage: Room temperature (20–25 °C) until opened.

• After opening: Should be used within 28 days due to benzyl alcohol preservation limits.

• Precaution: Not recommended in neonatal use (benzyl alcohol may be toxic to infants).
