Description
alpha-Naphtholphthalein is an organic compound that functions as a pH indicator, exhibiting color changes in response to variations in pH levels. It is characterized by its colorless appearance at a pH of 7.3 and a reddish color at a pH of 8.7, with a greenish to blue hue at a pH of 8.7. This property makes it particularly useful for detecting weak acids in strong alcoholic solutions.
Uses
Used in Chemical Industry:
alpha-Naphtholphthalein is used as a pH indicator in a 0.1% or 0.04% solution in alcohol. It is particularly adapted for detecting weak acids in strong alcoholic solutions due to its color change properties.
Used in Manufacturing and Electronics Industry:
alpha-Naphtholphthalein is used in the preparation of epoxy resin compounds, which are essential for manufacturing laminated boards, printed circuit boards, and other cured products with high heat resistance and flame retardancy. Its incorporation into these materials enhances their performance and safety characteristics.
Check Digit Verification of cas no
The CAS Registry Mumber 596-01-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 596-01:
(5*5)+(4*9)+(3*6)+(2*0)+(1*1)=80
80 % 10 = 0
So 596-01-0 is a valid CAS Registry Number.
