Description
BAC Water, commonly referred to as Bacteriostatic Water, is a preserved aqueous solution supplied for controlled laboratory, analytical, and scientific research applications.
It is commonly formulated with purified water and a low concentration of benzyl alcohol as a preservative. Because BAC Water is a mixture rather than one chemically defined substance, the complete formulation does not have a single molecular formula, molecular weight, CAS number, or amino-acid sequence.
The exact preservative concentration, water specification, sterility status, purity parameters, and lot-specific composition should be confirmed using the applicable product label and Certificate of Analysis.
Common Composition
A commonly referenced formulation contains:
99.1% Water
0.9% Benzyl Alcohol
Water
CAS #: 7732-18-5
Molecular Formula: H₂O
Molecular Weight: 18.015 g/mol
Benzyl Alcohol
CAS #: 100-51-6
Molecular Formula: C₇H₈O
Molecular Weight: Approximately 108.14 g/mol
The exact formulation should not be assumed unless confirmed by product-specific documentation.
Research Applications
BAC Water may be used in controlled laboratory research involving:
Aqueous formulation studies
Solution-preparation research
Analytical method development
Preservative-system characterization
Laboratory compatibility assessment
Stability studies
General research-solution preparation
Any laboratory use should remain within established procedures and the specifications stated in the applicable product documentation.
Analytical Identification
Relevant analytical characterization may include:
Water-quality assessment
Benzyl alcohol concentration verification
pH testing
Appearance and clarity assessment
Preservative-content analysis
Sterility or microbiological testing, where specified
Lot-specific quality analysis
Specifications & Documentation
Lot-specific documentation should be reviewed for:
Water specification
Preservative identity
Benzyl alcohol concentration
pH range
Purity parameters
Sterility status, where applicable
Analytical testing
Lot or batch information
Certificate of Analysis
Storage requirements
Expiration or retest information
Authenticated product-specific documentation takes precedence over general BAC Water formulation references.
Storage & Handling
Store according to the conditions specified on the product label and Certificate of Analysis. Keep the container properly closed and protect the solution from environmental conditions that could compromise product integrity.
Follow established laboratory procedures for preserved aqueous research solutions.
Research Use Only
BAC Water is supplied exclusively for laboratory research, analytical testing, and scientific reference purposes.
