14314-42-2 Usage
Description
Heavy-oxygen water, also known as Water-18O, is a form of water consisting of two hydrogen atoms covalently bonded to an oxygen-18 atom. It is a colorless liquid and has a high percentage of 18O, with 97 atom % 18O.
Uses
1. Used in DNA Stable Isotope Probing (SIP):
Heavy-oxygen water is used as a tracer for DNA stable isotope probing (SIP) to investigate microbial growth and death in environmental samples.
2. Used in Positron Emission Tomography (PET) Applications:
Heavy-oxygen water is used as an isotopically modified water for PET applications, which is a medical imaging technique that helps visualize the metabolic processes within the body.
3. Used in Paleoclimatology:
Heavy-oxygen water is used as a tool in paleoclimatology to determine the stable oxygen isotope analysis of plant cellulose using δ18O, which can provide insights into past climatic conditions.
4. Used in Hydrology:
In hydrology, heavy-oxygen water is used to determine the diffusion of moisture into crystals using secondary ion mass spectrometry (SIMS), which can help in understanding water movement and distribution in various geological formations.
5. Used in Plant Ecology:
Heavy-oxygen water is used in plant ecology to study the stable oxygen isotope analysis of plant cellulose using δ18O, which can provide information about the plant's water source and its adaptation to different environmental conditions.
Check Digit Verification of cas no
The CAS Registry Mumber 14314-42-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,3,1 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 14314-42:
(7*1)+(6*4)+(5*3)+(4*1)+(3*4)+(2*4)+(1*2)=72
72 % 10 = 2
So 14314-42-2 is a valid CAS Registry Number.
