Phosphate Buffer Market Projected to Hit USD 1,200 Million by 2035, at a Exceptional CAGR 4.4%

A phosphate buffer is a solution containing a mixture of phosphoric acid and its salts, used to maintain a stable pH in chemical, biological, and pharmaceutical applications. It resists changes in acidity or alkalinity, supporting enzyme reactions, cell culture, drug formulations, and analytical experiments where precise pH control is essential.
Published 07 November 2025

Phosphate buffers are chemical solutions that maintain stable pH levels in various biological, chemical, and industrial applications. Comprising monobasic and dibasic phosphate salts, these buffers resist changes in pH when acids or bases are added, making them essential in laboratory experiments, pharmaceutical formulations, food processing, and biochemical research.

The Phosphate Buffer Market Size was valued at 700 USD Million in 2024. The Phosphate Buffer Market is expected to grow from 800 USD Million in 2025 to 1,200 USD Million by 2035. The Phosphate Buffer Market CAGR (growth rate) is expected to be around 4.4% during the forecast period (2025 - 2035).

The global phosphate buffer market is growing steadily, driven by increasing demand in research and development, pharmaceutical manufacturing, biotechnology, and food and beverage industries. Their reliability in maintaining pH stability, combined with biocompatibility, makes phosphate buffers indispensable in processes such as enzyme assays, protein purification, and fermentation.
