712-48-1 Usage
General Description
A colorless crystalline solid, or a dark-brown liquid. Strongly irritating to skin and eyes. Toxic by ingestion and inhalation. Used as a military poison gas.
Air & Water Reactions
Slowly decomposed by water [Hawley].
Reactivity Profile
DIPHENYL CHLOROARSINE is incompatible with strong oxidizing agents, amines, and alkalis. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].
Health Hazard
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.
Safety Profile
A human poison by
inhalation. Poison experimentally by
inhalation and skin contact. A powerfully
irritating military poison. Exposure yields
cold-like symptoms, plus headache,
vomiting and nausea. A nonpersistent gas.
Decontamination is by use of chlorine or
caustic soda in confined spaces. When
heated to decomposition it emits toxic fumes of As and Cl-. See also ARSENIC
COMPOUNDS.
Check Digit Verification of cas no
The CAS Registry Mumber 712-48-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,1 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 712-48:
(5*7)+(4*1)+(3*2)+(2*4)+(1*8)=61
61 % 10 = 1
So 712-48-1 is a valid CAS Registry Number.

Insertion of benzyne into a Bi-S bond: A new synthetic route to ortho -functionalized bismuthanes and its application to the synthesis of dibenzothiophene

ortho-Arylthio triarylbismuthanes [2-(Ar′S)C6H 4]nBiAr3-n have been conveniently synthesized by insertion of benzyne into the bismuth-sulfur bond of (Ar′S) nBiAr3-n (n = 1, 2). A similar insertion takes place when a homologous antimony congener is used, but no reaction is observed with its phosphorus analogue. This suggests a clear difference in the bond strength between pnictogen-sulfur bonds. The carbon-bismuth bond of [2-(2-BrC 6H4S)C6H4]nBiAr 3-n undergoes Pd-catalyzed intramolecular cross-coupling to produce dibenzothiophene in good yield. An X-ray crystallographic study of 2-(2-BrC 6H4S)C6H4BiTol2 (Tol = 4-MeC6H4) reveals that this molecule is present in a dimeric structure, where the six heteroatoms including bismuth, sulfur, and bromine are linked through the nonbonded intramolecular bismuth-sulfur and intermolecular sulfur-bromine and bromine-bromine interactions.
