1340-26-7 Usage
Uses
Used in Chemical Analysis:Phenacetolin is used as an indicator for detecting the presence and concentration of alkali hydroxides and carbonates in mixtures. The color of the indicator changes from yellow to red when hydroxide is neutralized, and then back to yellow when carbonate is fully decomposed by an acid. This property makes it a valuable tool in chemical analysis and research.
Used in Water Quality Assessment:
Phenacetolin is also used for determining the alkalinity of water. By measuring the color change of the indicator, it is possible to assess the pH level and alkalinity of a water sample, which is crucial for understanding the water's quality and suitability for various purposes.
Preparation of Indicator Solution:
The indicator solution is prepared by digesting 1 gram of Phenacetolin with 100 milliliters of warm alcohol and filtering the mixture after it has cooled. For use, 2-3 drops of the prepared solution are added to 100 milliliters of the liquid being tested. This method allows for accurate and efficient detection of the target substances in a variety of applications across different industries.
Check Digit Verification of cas no
The CAS Registry Mumber 1340-26-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,4 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.Calculate Digit Verification of CAS Registry Number 1340-26:
(6*1)+(5*3)+(4*4)+(3*0)+(2*2)+(1*6)=47
47 % 10 = 7
So 1340-26-7 is a valid CAS Registry Number.
