71005-33-9 Usage
General Description
4-Aminodiphenylamine sulfate is a chemical compound that is commonly used in hair dyes and is also known as 4-ADPA. It is a synthetic chemical that is primarily used as an intermediate in the production of other chemicals, but it can also be used as a dye and colorant in various products. The sulfate form of 4-ADPA is water-soluble, making it suitable for use in aqueous formulations. However, 4-ADPA has been identified as a potential human carcinogen, and prolonged exposure to the chemical may pose health risks such as skin irritation, eye irritation, and respiratory tract irritation. Therefore, its use in consumer products is tightly regulated.
Check Digit Verification of cas no
The CAS Registry Mumber 71005-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,0 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 71005-33:
(7*7)+(6*1)+(5*0)+(4*0)+(3*5)+(2*3)+(1*3)=79
79 % 10 = 9
So 71005-33-9 is a valid CAS Registry Number.

Synthesizing method for diazonium monomer 4-diazo diphenylamine disulfate
-
Paragraph 0019, (2016/10/10)
The invention discloses a synthesizing method for a diazonium monomer 4-diazo diphenylamine disulfate, and belongs to the technical field of synthesis of photosensitive compounds.The 4-diazo diphenylamine disulfate is prepared by taking an RT base, concentrated sulfuric acid and sodium nitrite as raw materials and dropwise adding concentrated sulfuric acid and sodium nitrite.In the reaction process, ethyl alcohol is not needed to serve as solvent, and 4-diazo diphenylamine salt does not need to be synthesized and then replaced with concentrated sulfuric acid.When 4-diazo diphenylamine disulfate is synthesized through the method, the cost is greatly lowered, the equipment utilization rate is increased, and the yield reaches 80% or above.
