593-57-7

Dimethylarsine, also known as (CH3)2As, is an organoarsenic compound that consists of two methyl groups (CH3) bonded to an arsenic atom. It is a colorless, volatile, and highly toxic gas with a strong, unpleasant odor. Dimethylarsine is a byproduct of the chemical industry, particularly in the production of certain pesticides and herbicides, and can also be found as a trace component in some natural gas deposits. Due to its toxicity, exposure to dimethylarsine can lead to severe health issues, including respiratory problems, skin irritation, and potential carcinogenic effects. As a result, it is crucial to handle and store dimethylarsine with extreme caution and in accordance with proper safety protocols.

593-57-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 593-57-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 593-57:
(5*5)+(4*9)+(3*3)+(2*5)+(1*7)=87
87 % 10 = 7
So 593-57-7 is a valid CAS Registry Number.

Mundt, Otto,Riffel, Heinz,Becker, Gerd,Simon, Arndt

, p. 952 - 958 (2007/10/02)

The molecular and crystal structures of the isotypic compounds tetramethyldiphosphane 1 and -diarsane 2 have been determined by single crystal X-ray diffraction (monoclinic; C2/m; Z = 2; 1/2: -155/-144 deg C; a = 540.6(2)/555.8(2); b = 1131.0(6)/1136.7(6); c = 602.5(2)/612.8(2) pm; β = 97.31(3)/95.24(3) deg; P-P 221.2(1)/As-As 242.9(1) pm.In accordance with the crystallographically imposed symmetry 2/m, the molecules adopt antiperiplanar conformation.Their crystal structures are closely related to those of the homologues tetamethyldistibane 3 and -dibismuthane 4.As found for the latter compounds, the E-E units (E = P, As) are also aligned in linear chains, but the intermolecular E...E contacts (P...P 381/As...As 370 pm) do not allow any extended interaction between molecules, which otherwise would result in thermochromic effects. - Keywords: Tetramethyldiphosphane, Tetramethyldiarsane, Conformation, Molecular Structure, Crystal Structure

Dehnert, Peter,Grobe, Joseph,Van, Duc Le

, p. 48 - 54 (2007/10/02)

A systematic study of the cleavage of element-element bonds in compounds of the type RnE-ERm (R = CH3, CF3; E = P, As, S, Se, Te; n, m = 1, 2) by the group IV A element hydrides Me3M'H (M' = Si, Ge, Sn; Me = CH3) has been carried out.To evaluate the reaction pathway, for a number of compounds the attack of H2O, CH3OH, HBr and HI has been investigated.Possible reaction intermediates have been synthesized by independent routes and tested under comparable conditions. - Keywords: Organoelement-Element Compounds, Perfluoromethyl Derivatives, NMR Spectra
