12044-49-4 Usage
Description
Magnesium arsenide, with the molecular formula Mg3As2 and a molecular weight of 223.6592 g/mol, is a covalent compound that can be prepared by the direct reaction between magnesium and arsenic elements. It is a deep-brown, X-ray amorphous powder that decomposes in contact with water and must be stored under dry conditions. Its density is 3.15 g/cm3, and it exists in two forms: the low-temperature cubic β-Mg3As2 and the high-temperature hexagonal α-Mg3As2. Both forms are semiconductors, with the latter having a band gap of 2.2eV (564 nm).
Uses
1. Used in Pest Control:
Magnesium arsenide was historically used as a rodenticide and insecticide due to its toxic properties. However, its toxicity to humans has led to its prohibition in the US and Europe.
Please note that the use of magnesium arsenide in pest control is now prohibited due to its toxicity to humans and potential environmental hazards. It is essential to consider safer alternatives for pest control in modern applications.
Check Digit Verification of cas no
The CAS Registry Mumber 12044-49-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,4 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 12044-49:
(7*1)+(6*2)+(5*0)+(4*4)+(3*4)+(2*4)+(1*9)=64
64 % 10 = 4
So 12044-49-4 is a valid CAS Registry Number.
