18933-45-4 Usage
General Description
Tyrosine, 2,3,5,6-tetrafluoro- is a modified form of the amino acid tyrosine, with four fluorine atoms attached to the carbon atoms in the 2, 3, 5, and 6 positions. It is commonly used in research and pharmaceutical development as a precursor for the synthesis of various fluorinated compounds. The addition of fluorine atoms to the tyrosine molecule can alter its chemical and biological properties, potentially leading to new and improved drug candidates. Studies have shown that fluorinated tyrosine derivatives exhibit altered binding properties to certain receptors and enzymes, making them valuable tools in drug discovery and development. Additionally, these compounds have also been studied for their potential applications in imaging and diagnostics, particularly in the field of positron emission tomography (PET) imaging. Overall, tyrosine, 2,3,5,6-tetrafluoro- is a valuable chemical building block with promising applications in various fields of science and medicine.
Check Digit Verification of cas no
The CAS Registry Mumber 18933-45-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,3 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 18933-45:
(7*1)+(6*8)+(5*9)+(4*3)+(3*3)+(2*4)+(1*5)=134
134 % 10 = 4
So 18933-45-4 is a valid CAS Registry Number.
