1. Core Specifications & Quality Parameters

2. Key Functions & Advantages

Core Roles

1. Reconstitution Medium: Dissolves lyophilized peptides, hormones, and injectable powders without denaturing biomolecules.
2. Bacteriostatic Preservation: 0.9% benzyl alcohol inhibits bacterial/fungal growth, preventing contamination after vial puncture.
3. Multi-Dose Compatibility: Enables repeated draws from a single vial over 28 days (vs. single-use for plain sterile water).
4. Stability Enhancement: Extends the shelf life of reconstituted peptides (e.g., 72h for plain water vs. 7–14 days with BAC water at 2–8°C).

Key Advantages vs. Alternatives

3. Mechanism of Action (Benzyl Alcohol)

1. Membrane Disruption: Interacts with bacterial cell membranes, increasing permeability and disrupting ion balance, inhibiting growth (not sporicidal—effective against vegetative bacteria/fungi).
2. Enzyme Inhibition: Blocks microbial metabolic enzymes (e.g., alcohol dehydrogenase), suppressing replication without damaging mammalian cells at 0.9% concentration.

4. Usage Guidelines (Peptide Reconstitution)

Step 1: Aseptic Preparation

• Use sterile gloves, alcohol swabs, and a laminar flow hood (preferred) to avoid contamination.
• Allow BAC water vial to reach room temp before use (prevents condensation).

Step 2: Reconstitution Protocol

1. Calculate volume: Use 1–5 mL BAC water per 10–50 mg peptide (adjust for desired concentration, e.g., 1 mg/mL).
2. Reconstitute: Inject BAC water slowly along the vial wall; swirl gently (no shaking) to avoid foam/denaturation.
3. Let stand: Allow 5–10 minutes for full dissolution (especially for hydrophobic peptides).

Step 3: Storage Post-Reconstitution

• Store at 2–8°C; avoid freezing.
• Label vial with date/time of reconstitution; discard after 14 days (or 28 days for BAC water itself).

5. Safety & Handling Precautions

Critical Warnings

1. Contraindications: Not for direct IV injection (hypotonic); avoid use in neonates (benzyl alcohol toxicity risk).
2. Adverse Reactions: Rare—local irritation (if benzyl alcohol concentration exceeds 0.9%); hypersensitivity (discontinue if rash/swelling occurs).
3. Research Use: For laboratory/research only; clinical use requires ethical approval and regulatory compliance.

Handling Best Practices

• Use sterile syringes/needles for each draw; avoid touching the rubber stopper with non-sterile surfaces.
• Do not mix with incompatible substances (e.g., strong acids/bases, oxidizers).
• Dispose of vials/syringes per biomedical waste regulations.

6. Quality Control & Production

Manufacturing Standards

1. Source Water: WFI purified via distillation/RO/ultrafiltration to meet USP/EP standards.
2. Benzyl Alcohol: Pharmaceutical-grade (≥99.5% purity); added under aseptic conditions.
3. Sterilization: Autoclaving or filtration through 0.22 μm membranes post-filling.
4. Testing: Each batch undergoes HPLC (purity), endotoxin, sterility, and pH verification.
