Benzyl Alcohol

Overview

Benzyl alcohol is a simple aromatic alcohol with the molecular formula C7H8O — a colorless, clear liquid at room temperature with a density of about 1.044-1.045 g/cm3, a boiling point of roughly 204-206°C, and a mild aromatic odor (independently re-confirmed via PubChem CID 244 in this review). In the RUO/pharmaceutical setting, its primary use is as the antimicrobial preservative in Bacteriostatic Water for Injection, USP (0.9% benzyl alcohol, FDA-approved, documented in DailyMed), used to reconstitute multi-dose lyophilized peptide powders (e.g., BPC-157, TB-500, semaglutide) and extend the usable life of the s… Vialdyne supplies Benzyl Alcohol as clear, colorless liquid with a batch-specific Certificate of Analysis covering identity, assay, and appearance. The applicable batch COA identifies the specification used and records the actual results.

Applications & buyer fit

Custom-blend buyers are almost always OEM clients building a branded product around a specific ratio of two or more peptides. The development workflow is collaborative: ratio target, analytical method to verify it, stability protocol in the chosen carrier, and packaging selection are all defined in the OEM brief before the first commercial run. Sample-stage volumes are usually 5-10 g of finished blend; commercial MOQ depends on the components.

Primary buyer fit: academic and contract research laboratories.
