823-47-2 Usage
General Description
Ethyl propiolate is a chemical compound with the molecular formula C5H6O2. It is a clear, colorless liquid with a characteristic fruity odor. Ethyl propiolate is commonly used as a flavoring agent in the food industry, imparting a fruity and sweet taste to various products. It is also utilized as a synthetic building block in the production of pharmaceuticals, agrochemicals, and other organic compounds. Ethyl propiolate has low water solubility and is flammable, posing potential hazards in handling and storage. It is important to follow proper safety precautions when working with this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 823-47-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 823-47:
(5*8)+(4*2)+(3*3)+(2*4)+(1*7)=72
72 % 10 = 2
So 823-47-2 is a valid CAS Registry Number.

A series of derivatives of 2-aminopyridine, 2-(ethylamino)pyridine, and 1-ethyl-2-imino-1,2-dihydropyridine formed with diisopropylphosphinous esters were obtained.The structure of the compounds was studied. (2-Pyridylamino)diisopropylphosphine was alkylated with triethyloxonium tetrafluoroborate to a quasiphosphonium salt and was protonated with hydrogen chloride at the endocyclic nitrogen atom to give a pyridinium salt.Protonation with fluoroboric acid results in a complex mixture of three products.The methanolysis of P(III)-phosphorylated 2-aminopyridines and their derivatives was studied.These investigations demonstrated that amides capable of prototropic transformations exhibit markedly enhanced phosphorylating activity.
