534-13-4 Usage
Description
N,N'-DIMETHYLTHIOUREA, also known as Dimethylthiocarbamide, is an antioxygen agent that is colorless to white in appearance and exists in the form of crystals or crystalline powder. It is primarily known for its role in preventing sensitization when unexposed to light, particularly in the context of diazo papers.
Uses
Used in Chemical Synthesis:
N,N'-DIMETHYLTHIOUREA is used as an intermediate in the preparation of Arginine derivatives, which are essential for various chemical and pharmaceutical applications.
Used in Paper Industry:
N,N'-DIMETHYLTHIOUREA is used as an antioxidant in diazo copy paper to prevent yellow discoloration of the paper, ensuring that the final product maintains its quality and appearance over time.
Contact allergens
Dimethylthiocarbamide, an antioxygen agent, is responsible for sensitization, when unexposed to light from diazo papers.
Safety Profile
Moderately toxic by
ingestion. Experimental teratogenic and
reproductive effects. When heated to
decomposition it emits toxic fumes of SOx
andNO,.
Check Digit Verification of cas no
The CAS Registry Mumber 534-13-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 534-13:
(5*5)+(4*3)+(3*4)+(2*1)+(1*3)=54
54 % 10 = 4
So 534-13-4 is a valid CAS Registry Number.
