625-22-9 Usage

Chemical Properties

Colorless liquid; sharp characteristic odor;boils at 115°C (239°F) at 6 torr; density 1.06at 20°C (68°F); insoluble in water; soluble inalcohol and ether.

Health Hazard

The toxicity of this substance is much lowerthan the methyl or the ethyl sulfate esters.It is moderately toxic by ingestion. Theoral lethal dose in rabbits is within therange 200 mg/kg. Studies on experimentalanimals indicate a mild toxic action whenadministered by subcutaneous route.LD50 , skin (rat): 5000 mg/kg.

Safety Profile

oison by ingestion. Mildly toxic by subcutaneous route. Questionable carcinogen with experimental tumorigenic data. See also ESTERS and SULFATES. When heated to decomposition it emits toxic fumes of Sox.

Check Digit Verification of cas no

The CAS Registry Mumber 625-22-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 625-22:
(5*6)+(4*2)+(3*5)+(2*2)+(1*2)=59
59 % 10 = 9
So 625-22-9 is a valid CAS Registry Number.

Reactions of Group V Metal Compounds with Sulfur Trioxide

Ando, Fumio,Koketsu, Jugo,Ishii, Yoshio

, p. 3495 - 3499 (2007/10/02)

Trialkylphosphines react with equimolar amounts of sulfuric trioxide to form the 1:1 adducts R3P(1+)-SO3(1-).Trialkylarsines and -stibines undergo sulfur trioxide insertion reaction across the metal-carbon bond to give the trisulfonates of the metal M(OSO2R)3 (M=As,Sb).The reactions of trialkyl phosphites, with sulfur trioxide yield trialkyl phosphonates, trialkyl thiophosates, dialkyl alkylphosphonates, dialkyl sulfates, and polymers which contain phosphorus atoms.The reactions of trialkoxyarsines and -stibines result in the insertion of sulfur trioxide across the metal-oxygen bond to form the alkoxymetal alkylsulfates (RO)3-nM(OSO3R)n (M=As,Sb; n=1,2,3) depending on the stoichiometric ratios of the reagents used.Pyrolysis of the metal sulfates gives dialkyl sulfates and undistillable residues containing the metals.
