Drabkins solution by Research Lab Fine Chem Industries is a high grade reagent. This reagent solution is used for the determination of haemoglobin concentration in blood. The reagent is available as a liquid solution. It reacts with all forms of hemoglobin except sulfhemoglobin, which is a pigment that normally occurs in only tiny concentrations in the blood. While it is stable under general conditions, this reagent is incompatible with strong oxidizing agents. Quantity Provided: 500 ml per bottle DiluentDrabkins solution has a variety of applications in chemical and biological sectors. This compound finds several applications in the synthesis of various organic derivatives. Drabkins Reagent is utilized for the quantitative colorimetric determination of hemoglobin concentration in whole blood. The test is centred on the oxidation of hemoglobin and its derivatives (except sulfhemoglobin) to methemoglobin, which occurs in the presence of alkaline potassium ferricyanide. Cyanmethemoglobin, which is formed from methemoglobin reacting with potassium cyanide, has maximum absorbance at 540 nm. This reagent is suitable for the industrial synthesis of products and research applications.
