The Resazurin Sodium Salt market is projected to witness steady growth in the coming years, driven by its increasing use in cell viability assays, redox reactions, and biochemical research.
Published 17 August 2025

Resazurin sodium salt is a versatile chemical compound widely recognized for its role as a redox indicator in biological, biochemical, and industrial applications. Known for its distinct colorimetric and fluorometric properties, it has become an indispensable tool in cell viability assays, microbiological testing, and metabolic activity measurements. The compound operates on a well-defined principle: in the presence of active metabolism, resazurin is reduced to resorufin, a highly fluorescent and visibly pink compound. This transformation makes it an excellent marker of cellular activity, bacterial contamination, and redox changes.

The simplicity, reliability, and sensitivity of resazurin sodium salt have made it a standard reagent in laboratories worldwide. Beyond research, it finds roles in industrial microbiology, water testing, and even food safety analysis. With growing interest in rapid diagnostic tools, resazurin sodium salt continues to gain attention as a low-cost yet highly effective solution.

The Resazurin Sodium Salt Market Size was estimated at 1.73 (USD Billion) in 2023. The Resazurin Sodium Salt Market Industry is expected to grow from 1.83(USD Billion) in 2024 to 2.8 (USD Billion) by 2032. The Resazurin Sodium Salt Market CAGR (growth rate) is expected to be around 5.48% during the forecast period (2024 - 2032).
