67668-19-3 Usage
Uses
Used in Chemical Industry:
1-Naphthalenamine, 4-ethylis used as an intermediate in the production of dyes and pigments for its ability to contribute to the color and stability of these products.
Used in Lubricant Industry:
1-Naphthalenamine, 4-ethylis used as a corrosion inhibitor in lubricating oils to prevent the degradation of the oil and protect the machinery from corrosion.
Used in Rubber Industry:
1-Naphthalenamine, 4-ethylis used as a rubber antioxidant to prevent the oxidation of rubber, thereby extending its lifespan and maintaining its properties.
Safety Precautions:
It is important to handle 1-Naphthalenamine, 4-ethylwith caution as it has been classified as a potential skin and eye irritant and may cause allergic reactions in some individuals. Proper protective measures should be taken during its use and handling.
Check Digit Verification of cas no
The CAS Registry Mumber 67668-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,6 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 67668-19:
(7*6)+(6*7)+(5*6)+(4*6)+(3*8)+(2*1)+(1*9)=173
173 % 10 = 3
So 67668-19-3 is a valid CAS Registry Number.

Revitalizing the aromatic aza-Claisen rearrangement: Implications for the mechanism of 'on-water' catalysis
Beare, Kaitlin D.,McErlean, Christopher S. P.
, p. 2452 - 2459 (2013/06/05)
For too long the aromatic aza-Claisen rearrangement has been the poor relation of its oxygen counterpart. We demonstrate that on-water catalysis facilitates the rearrangement of reverse N-prenylated naphthylamines and anilines, and transforms the aromatic
