7137-84-0 Usage
Class
Organophosphorus compounds
Subclass
Phosphine oxides
Structure
Five-membered phospholane ring attached to a pyrrolidine ring
Applications
a. Ligands in organometallic chemistry
b. Intermediates in organic synthesis
c. Potential applications in pharmaceuticals and materials science
Chemical properties
a. Heteroatomic ring system containing phosphorus
b. Basic nitrogen atoms from the pyrrolidine ring
c. Steric hindrance due to methyl groups on the phospholane ring
Physical properties
a. Likely a solid at room temperature (based on molecular size and complexity)
b. Insoluble or poorly soluble in water (due to nonpolar nature and lack of polar functional groups)
c. Soluble in organic solvents (e.g., dichloromethane, acetone, or ethanol)
Synthesis
a. Multi-step process involving the formation of the phospholane ring and subsequent functionalization with the pyrrolidine moiety
b. Requires careful control of reaction conditions to avoid side reactions and ensure product purity
Stability
a. Stable under normal laboratory conditions
b. May be sensitive to strong acids, bases, or oxidizing agents (due to the presence of the phosphorus atom and basic nitrogen atoms)
Hazards
a. Potential irritant or toxic (due to the presence of a phosphorus-containing ring and basic nitrogen atoms)
b. Proper handling and storage required to minimize exposure risks
c. Disposal should follow chemical waste management guidelines
Check Digit Verification of cas no
The CAS Registry Mumber 7137-84-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,3 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7137-84:
(6*7)+(5*1)+(4*3)+(3*7)+(2*8)+(1*4)=100
100 % 10 = 0
So 7137-84-0 is a valid CAS Registry Number.
