Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
Accurate determination of serum calcium levels is critical in clinical diagnostics, impacting patient health assessments and treatment plans. O-Cresolphthalein Complexone (CAS 2411-89-4) emerges as a key reagent in this process, serving as a precise indicator for calcium measurement. As a dedicated manufacturer and supplier of high-quality chemical compounds, we are pleased to offer this essential product to the global market.
The Chemical Profile of O-Cresolphthalein Complexone
O-Cresolphthalein Complexone is a fine powder, typically white to off-white in color, with a molecular formula of C32H32N2O12 and a molecular weight of 636.61. Its purity, guaranteed at ≥97.0%, ensures that it functions effectively as both a metal complex indicator and an acid-base indicator. The characteristic color transition from colorless at pH 8.2 to red at pH 9.8 is fundamental to its application in detecting the presence and concentration of specific metal ions, most notably calcium.
Critical Role in Serum Calcium Analysis
In clinical laboratories, o-Cresolphthalein Complexone is widely employed in colorimetric methods for determining serum calcium. It reacts with calcium ions in a buffered solution to form a distinct colored complex, the intensity of which is directly proportional to the calcium concentration. This makes it an indispensable tool for accurate and efficient diagnostic testing. For laboratories seeking to buy this vital reagent, ensuring its quality and availability is paramount. We provide this product with the assurance of high purity and consistent performance, positioning us as a reliable supplier in China.
