231953-15-4 Usage
General Description
4-(Trimethylammonium)-2,2,6,6-tetramethylpiperidine-d17-1-oxyl iodide is a stable free radical, also known as a spin label, commonly used in electron paramagnetic resonance (EPR) studies to study the structure and dynamics of biological molecules. It is a deuterated derivative of the stable free radical TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl), and its positively charged trimethylammonium group makes it highly water-soluble. This property allows for its use in studying biological systems and membranes through EPR spectroscopy. Additionally, the presence of iodide in the molecule enhances its chemical properties and reactivity, making it a versatile tool for various research applications in chemistry and biochemistry.
Check Digit Verification of cas no
The CAS Registry Mumber 231953-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,1,9,5 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 231953-15:
(8*2)+(7*3)+(6*1)+(5*9)+(4*5)+(3*3)+(2*1)+(1*5)=124
124 % 10 = 4
So 231953-15-4 is a valid CAS Registry Number.
