13306-67-7 Usage
General Description
Phenolphthalein monophosphate is a chemical compound commonly used as an indicator in acid-base titrations and as a colorimetric reagent. It is a derivative of phenolphthalein, a widely used pH indicator, and is selectively cleaved by alkaline phosphatase to form phenolphthalein, which produces a pink color in basic solutions. This property makes it useful for the detection and quantification of alkaline phosphatase activity in biological samples, such as serum and urine. Phenolphthalein monophosphate is also used in molecular biology and biochemistry research as a substrate for the measurement of alkaline phosphatase activity in enzyme-linked immunosorbent assays (ELISA) and other biochemical assays.
Check Digit Verification of cas no
The CAS Registry Mumber 13306-67-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,0 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 13306-67:
(7*1)+(6*3)+(5*3)+(4*0)+(3*6)+(2*6)+(1*7)=77
77 % 10 = 7
So 13306-67-7 is a valid CAS Registry Number.
