699-25-2 Usage
General Description
3,5-diethyl pyridine is a chemical compound with the molecular formula C9H13N. It is a derivative of pyridine and consists of a pyridine ring with two ethyl groups attached to the 3rd and 5th carbon atoms. This chemical is commonly used as a building block in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds. It is known for its strong odor and is used as a flavoring agent in the food industry. Additionally, 3,5-diethyl pyridine has been found to exhibit insecticidal properties and is used in the formulation of insecticides. However, it is important to handle this chemical with care, as it is toxic and can cause irritation to the skin, eyes, and respiratory system.
Check Digit Verification of cas no
The CAS Registry Mumber 699-25-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 699-25:
(5*6)+(4*9)+(3*9)+(2*2)+(1*5)=102
102 % 10 = 2
So 699-25-2 is a valid CAS Registry Number.

Abstract: The catalytic properties of samples of amorphous mesoporous aluminosilicate ASM with different Si/Al molar ratios (40, 80, 160) were studied in the synthesis of practically important pyridines (by the interaction of С2–С5 alcohols with formaldehyde and ammonia, cyclocondensation of acetaldehyde and propionic aldehyde with ammonia), dialkylquinolines and alkyltetrahydroquinolines (by reaction of aniline with C3, C4 aldehydes) and alkyldihydroquinolines (by interaction of aniline with ketones, acetone and acetophenone). It is found that mesoporous aluminosilicate ASM sample with a molar ratio of Si/Al = 40, which has the highest acidity among the studied samples, exhibits the highest activity and selectivity in these reactions.
