23647-14-5 Usage
Description
SPADNS, or Sulfanilic acid azochromotrop, is a dark red-brown crystalline powder that is primarily used as an indicator in complexometric determinations of zirconium and thorium. It is also utilized as a reagent in the analysis of drinking and wastewater, specifically through the Hach Method 8029, Fluoride, SPADNS Method.
Uses
Used in Analytical Chemistry:
SPADNS is used as an indicator for complexometric determinations of zirconium and thorium, aiding in the accurate measurement and analysis of these elements in various samples.
Used in Environmental Science:
In the field of environmental science, SPADNS is used as a reagent for drinking and wastewater analysis. It plays a crucial role in the Hach Method 8029, Fluoride, SPADNS Method, which is a widely accepted technique for assessing the quality of water sources and ensuring their safety for consumption and use.
Used in Water Treatment Industry:
SPADNS is employed in the water treatment industry to ensure that the water being supplied for drinking and other purposes meets the required standards. By being a part of the Hach Method 8029, it helps in identifying and quantifying the presence of fluoride in water, which is essential for maintaining the overall water quality and public health.
Check Digit Verification of cas no
The CAS Registry Mumber 23647-14-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,6,4 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 23647-14:
(7*2)+(6*3)+(5*6)+(4*4)+(3*7)+(2*1)+(1*4)=105
105 % 10 = 5
So 23647-14-5 is a valid CAS Registry Number.
