99892-20-3 Usage
Chemical structure
A cyclic tetraamine with three sulfonyl groups attached to the 1st, 4th, and 7th nitrogen atoms, and a methylsulfonyl group attached to the 10th nitrogen atom.
Functional groups
Sulfonyl groups (-SO2-) and methylsulfonyl group (-SO2CH3).
Coordination chemistry
Commonly used as a chelating agent in the synthesis of metal complexes.
Applications in medicine
Potential use as a carrier for targeted drug delivery and in imaging agents for diagnostic purposes.
Unique properties
The complex structure and properties make it valuable in various scientific and industrial fields.
Molecular weight
Approximately 569.76 g/mol
Solubility
Soluble in organic solvents such as dimethyl sulfoxide (DMSO) and dimethylformamide (DMF).
Stability
Generally stable under normal conditions, but sensitive to strong acids and bases.
Synthesis
Typically synthesized through a multi-step process involving the formation of the cyclic tetraamine core and subsequent attachment of the sulfonyl and methylsulfonyl groups.
Check Digit Verification of cas no
The CAS Registry Mumber 99892-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,9 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99892-20:
(7*9)+(6*9)+(5*8)+(4*9)+(3*2)+(2*2)+(1*0)=203
203 % 10 = 3
So 99892-20-3 is a valid CAS Registry Number.
