3-Hydroxy-3-phenyl-3-pyridin-4-yl-propionic acid ethyl ester, also known as etofenprox, is a synthetic chemical compound belonging to the class of pyridine derivatives. It is primarily used as an insecticide, specifically targeting pests such as aphids, whiteflies, and leafhoppers. The compound is characterized by its ability to disrupt the molting process of insects, leading to their death. Etofenprox is widely employed in agriculture to protect crops from damage caused by various insect species. It is known for its effectiveness and low mammalian toxicity, making it a popular choice in integrated pest management strategies. However, it is crucial to follow proper application guidelines and safety measures to minimize potential environmental and health risks associated with its use.

2293-57-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2293-57-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,9 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2293-57:
(6*2)+(5*2)+(4*9)+(3*3)+(2*5)+(1*7)=84
84 % 10 = 4
So 2293-57-4 is a valid CAS Registry Number.

Ethyl (tributylstannyl)acetate: A versatile reagent for the carboethoxymethylation of functionalized pyridines

Murali Dhar,Gluchowski, Charles

, p. 989 - 992 (1994)

Ethyl (tributylstannyl)acetate adds chemoselectively to acylpyridinium salts to yield a variety of dihydropyridines with diverse functional groups. These compounds are useful precursors for the preparation of a variety of N- heterocycles. The regiochemistry of the reaction is addressed and the results are rationalized based on the HSAB principle.
