GLP – 5 (R)

Product Overview:

1 Chemical Composition and Classification

BAC Water is a sterile aqueous solution containing benzyl alcohol (0.9 %, w/v) as an antimicrobial preservative in water for injection [1].This combination renders the solution bacteriostatic—capable of inhibiting bacterial growth—making it distinct from sterile water without additives [1]. Benzyl alcohol is an aromatic primary alcohol with a mild antimicrobial profile and is listed in the PubChem database under CID 244 [2].

2 Applications in Peptide and Protein Research

In peptide research, BAC Water is frequently employed to reconstitute lyophilized peptides prior to experimental assays [3]. The bacteriostatic property of benzyl alcohol allows repeated vial entry without significant risk of microbial contamination during the research period [3]. This is particularly advantageous for experiments requiring incremental sampling or extended timelines.

3 Role in Stability and Sample Integrity Studies

BAC Water’s benzyl alcohol component plays a key role in maintaining sterility, which can reduce the risk of peptide degradation caused by microbial enzymes [4]. Researchers often investigate how various diluents affect peptide stability, and BAC Water is a preferred control when evaluating antimicrobial preservation effects [4].

1 Microbiology and Antimicrobial Research

While BAC Water’s bacteriostatic nature offers distinct research benefits, certain cell culture applications avoid benzyl alcohol due to its potential cytotoxicity at higher concentrations [6]. PubChem data also notes that benzyl alcohol can disrupt certain enzymatic reactions in vitro [6]. Consequently, researchers carefully match the diluent to the specific assay requirements
