3-Thioxopropadien-1-one, also known as 3-mercapto-2-propenal or thioacrolein, is a sulfur-containing organic compound with the chemical formula C3H4OS. It is a colorless, highly reactive, and unstable liquid with a pungent, suffocating odor. 3-thioxopropadien-1-one is a key intermediate in the synthesis of various organic compounds, particularly those containing a carbon-sulfur double bond. Due to its reactivity, 3-thioxopropadien-1-one can readily undergo addition reactions, polymerization, and other chemical transformations. It is also known for its potential use as a building block in the production of pharmaceuticals, agrochemicals, and other specialty chemicals. However, it is important to note that 3-thioxopropadien-1-one is toxic and can cause severe health issues if not handled properly, necessitating careful handling and safety precautions during its use in chemical processes.

2219-62-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2219-62-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,1 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2219-62:
(6*2)+(5*2)+(4*1)+(3*9)+(2*6)+(1*2)=67
67 % 10 = 7
So 2219-62-7 is a valid CAS Registry Number.

A Contribution to the Direct Observation of a Didehydroheteroaromatic with a Five-Membered Ring: 2,3-Didehydrothiophene

Teles, Joaquim Henrique,Hess, Andes B.,Schaad, Lawrence J.

, p. 423 - 432 (2007/10/02)

The flash vacuum pyrolysis and the photolysis of 2,3-thiophenedicarboxylic acid anhydride (6) were investigated by using the technique of matrix isolation combined with FT-IR spectroscopy.No conclusive proof for the existence of 2,3-didehydrothiophene (1) could be found, but two hitherto unknown isomers were isolated and characterized: vinylidenethioketene (10) and thioformylvinylidenecarbene (15). Key Words: Matrix isolation / Photolysis / Vibrational spectra, theoretical / 2,3-Didehydrothiophene / Calculations, ab initio, semi-empirical
