14918-39-9 Usage
Uses
Used in Textile Industry:
ANTIPYRYLAZO III is used as a pH indicator for monitoring the acidity or alkalinity of dye baths during the dyeing process. Its color change from yellow to red in acidic conditions and from yellow to blue in alkaline conditions helps ensure the correct pH for optimal dye uptake and colorfastness of fabrics.
Used in Paper Industry:
In the paper industry, ANTIPYRYLAZO III serves as a pH indicator to control the pH levels of paper pulp during manufacturing. Maintaining the appropriate pH is crucial for the paper's quality, strength, and resistance to degradation.
Used in Laboratory Applications:
ANTIPYRYLAZO III is used as a reagent in the determination of metal ions, where its color change properties assist in identifying and quantifying the presence of specific metal ions in a sample.
Additionally, it is employed in spectrophotometric analysis, where its color change characteristics are utilized to measure the concentration of substances in a solution by comparing the absorbance of light at different wavelengths.
Safety Considerations:
While ANTIPYRYLAZO III is considered safe for use in the aforementioned applications, it is important to avoid exposure to large quantities of the compound, as it may cause skin and eye irritation. Proper handling and safety measures should be followed to minimize potential health risks.
Check Digit Verification of cas no
The CAS Registry Mumber 14918-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,9,1 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 14918-39:
(7*1)+(6*4)+(5*9)+(4*1)+(3*8)+(2*3)+(1*9)=119
119 % 10 = 9
So 14918-39-9 is a valid CAS Registry Number.
