The accurate measurement of pH is fundamental to countless scientific and industrial processes, from chemical synthesis to environmental monitoring. pH indicators, such as Cresol Red (CAS 1733-12-6), are indispensable tools for this purpose, offering visual cues to gauge acidity or alkalinity. As a prominent manufacturer and supplier of fine chemicals in China, we recognize the widespread utility of Cresol Red and are committed to providing a product that meets the highest standards of quality and performance.

Cresol Red, a member of the triarylmethane dye family, is particularly noted for its distinct pH-dependent color changes. While it can show transitions in the acidic range (pH 1.8-2.0, orange to yellow), its most commonly utilized range is in the neutral to slightly alkaline region. Between pH 7.0 and 8.8, Cresol Red transitions from a distinct yellow to a vibrant violet or red. This broad transition range makes it highly effective for titrations where the endpoint falls within this pH spectrum, such as in the analysis of weak acids or bases, or for buffer solutions. When you need to buy a reliable pH indicator for these applications, sourcing from a reputable China supplier ensures consistency.

The applications of Cresol Red as a pH indicator extend beyond simple titrations. It is used in analytical chemistry for qualitative and quantitative assessments of solution pH, in quality control laboratories to verify the pH of products, and even in biological studies where maintaining specific pH levels is critical for cell viability or enzyme activity. Its clear visual signal simplifies the process of pH determination, making it accessible even without specialized pH meters in some scenarios. For those seeking to purchase Cresol Red, understanding these applications helps in specifying the required purity and quantity.

As a manufacturer and supplier, we emphasize the importance of high-purity Cresol Red for accurate pH indication. Impurities can lead to blurred or shifted color transitions, compromising experimental results. Our commitment is to provide a product with an assay of 99% or higher, ensuring reliable performance. Procurement managers looking to buy Cresol Red should consider the source's reputation for quality control and supply chain reliability. Our manufacturing facility in China is equipped to produce and deliver Cresol Red efficiently, offering competitive pricing that makes high-quality reagents accessible.

In summary, Cresol Red (CAS 1733-12-6) is a highly effective pH indicator with valuable applications across various scientific disciplines. Its distinct color transitions in the neutral to alkaline pH range make it a preferred choice for many analytical tasks. We, as a trusted China-based manufacturer and supplier, are dedicated to delivering high-purity Cresol Red at competitive prices.
