Sodium dehydroacetate

Sodium dehydroacetate (CAS No.: 4418-26-2) is a synthetic pyranone derivative and the sodium salt form of dehydroacetic acid that is primarily classified as an antimicrobial preservative research reagent within microbiology, formulation science, and early stage anti infective screening workflows, where it is used to investigate broad inhibitory effects on bacteria and fungi and to model xenobiotic stress responses rather than target specific receptor pharmacology; current evidence indicates that its activity is predominantly associated with nonspecific disruption of microbial homeostasis, including membrane associated effects and interference with essential metabolic processes, while direct high confidence molecular targets and pathway selective mechanisms remain insufficiently resolved in public literature, so it is generally treated as a phenotypically active small molecule with context dependent action profiles, and reported in vitro potency is typically described at micromolar to millimolar exposure ranges depending on organism, medium composition, and assay format rather than as a single universal endpoint, with utility in antimicrobial susceptibility assays, preservative efficacy testing, contamination control studies, and comparative benchmarking of resistance related phenotypes in cell based and microorganism based models; in translationally oriented discovery settings it can also serve as a reference stressor for evaluating assay robustness, microbial burden reduction kinetics, and formulation driven modulation of bioactivity, whereas in vivo exploratory use is comparatively less standardized and is generally limited to non clinical experimental systems under institution specific safety and ethics frameworks, and the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
