7784-44-3 Usage
Chemical Properties
Ammonium arsenate a combustible, white powder
or plate-like colorless crystal.
General Description
A white crystalline solid. Toxic by ingestion.
Air & Water Reactions
Water soluble; decomposes in hot water [Handbook of Chemistry and Physics].
Reactivity Profile
Solutions of AMMONIUM ARSENATE are acidic. They neutralize bases in reactions that generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acids. Compounds usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.
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
Confirmed human
carcinogen. A poison. When heated to
decomposition it emits very toxic fumes of
As, NOx, and NH3. See also ARSENIC.
Shipping
UN1546 Ammonium arsenate, Hazard Class:
6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
Hydrogen gas forms highly toxic arsine
gas on contact with inorganic arsenic.
Waste Disposal
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations governing
storage, transportation, treatment, and waste disposal.
Check Digit Verification of cas no
The CAS Registry Mumber 7784-44-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7784-44:
(6*7)+(5*7)+(4*8)+(3*4)+(2*4)+(1*4)=133
133 % 10 = 3
So 7784-44-3 is a valid CAS Registry Number.
