The precise measurement and control of pH are fundamental in countless scientific and industrial processes, from chemical synthesis to biological culture maintenance. pH indicators, such as Neutral Red, are indispensable tools that provide visual cues for these critical parameters. Neutral Red (CAS 553-24-2), also known as C.I. 50040, is a fascinating dye that serves as both a vital stain and a versatile pH indicator, demonstrating distinct color changes within a specific pH range. As a leading manufacturer of chemical reagents, we are dedicated to supplying researchers with high-quality products like Neutral Red.

Neutral Red is a cationic dye belonging to the oxazine group. Its utility as a pH indicator stems from its molecular structure, which undergoes protonation and deprotonation, leading to altered light absorption properties. Specifically, Neutral Red exhibits a color transition from red to yellow as the pH shifts from acidic to alkaline. The primary transition range is typically cited between pH 6.8 and 8.0. This makes it particularly useful for monitoring physiological pH ranges or slightly alkaline conditions often encountered in biological systems and chemical reactions.

The application of Neutral Red as a pH indicator is widespread. In biological research, it can be used to monitor the pH of cell culture media, ensuring optimal conditions for cell growth and metabolic activity. Its ability to enter living cells and accumulate in lysosomes, where it maintains its pH-indicating property, further enhances its utility in studies involving intracellular pH dynamics. For researchers seeking to buy Neutral Red for these specific applications, ensuring the purity and performance of the dye is paramount. We, as a reliable supplier, guarantee the quality of our Neutral Red.

Beyond biological contexts, Neutral Red can also be employed in various chemical analyses where a visual pH endpoint is needed. Its distinct color change makes it an effective indicator for titrations or in formulations where pH stability is critical. For industries requiring bulk quantities, understanding where to purchase Neutral Red from a dependable manufacturer in China can significantly impact operational efficiency and cost-effectiveness. We offer competitive pricing and reliable supply chains.
