1665-59-4 Usage
General Description
N,N-Diethyl-N'-phenylethylenediamine, also known as DPED, is a chemical compound primarily used as an antioxidant to prevent or slow down the degradation of substances such as rubber, plastics, and lubricants. It is a clear, colorless to light yellow liquid characterized by a strong amine odor, and it is highly soluble in organic solvents. DPED functions by donating hydrogen atoms to free radicals, thereby stabilizing them and preventing oxidative damage. However, it should be handled with caution as it is considered to be harmful if swallowed or inhaled, and it may cause skin and eye irritation. Additionally, it may be toxic to aquatic life and has the potential to bioaccumulate.
Check Digit Verification of cas no
The CAS Registry Mumber 1665-59-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,6 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1665-59:
(6*1)+(5*6)+(4*6)+(3*5)+(2*5)+(1*9)=94
94 % 10 = 4
So 1665-59-4 is a valid CAS Registry Number.

Arylamines are manufactured by reacting alcohols with amines in the presence of phosphorus-III compounds. The arylamines I manufactured by the process of the invention are intermediates for the manufacture of crop protection agents, optical brighteners, especially amino-coumarin derivatives, and dyes, especially of the xanthene, pyronine, rhodamine, oxazine, azo, triphenylmethane and diphenylmethane series.
