134-54-3 Usage
Uses
Used in Dye and Pigment Production:
4-aminonaphthalene-2-sulphonic acid is used as a key intermediate in the production of dyes and pigments, particularly for the textile and paper industries. Its water solubility allows for easy incorporation into aqueous-based formulations, enhancing the coloration process and the quality of the final products.
Used as a pH Indicator:
Due to its chemical properties, 4-aminonaphthalene-2-sulphonic acid is utilized as a pH indicator, helping to monitor and control the acidity or alkalinity of various solutions in different industrial processes.
Used in Pharmaceutical and Agrochemical Synthesis:
4-aminonaphthalene-2-sulphonic acid serves as a building block in the synthesis of pharmaceuticals and agrochemicals, contributing to the development of new drugs and agricultural products.
However, it is important to note that 4-aminonaphthalene-2-sulphonic acid is considered toxic and may pose health and environmental hazards. Therefore, it requires careful handling, use, and disposal to minimize potential risks.
Check Digit Verification of cas no
The CAS Registry Mumber 134-54-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 134-54:
(5*1)+(4*3)+(3*4)+(2*5)+(1*4)=43
43 % 10 = 3
So 134-54-3 is a valid CAS Registry Number.
