Hey there! I'm a supplier of CAS 13674 - 84 - 5. Today, I wanna chat about the NMR methods for studying this chemical.
First off, let's get a bit of background. CAS 13674 - 84 - 5 is a compound that has various applications, especially in the field of flame - retardants. It's important to understand its structure and properties, and that's where NMR (Nuclear Magnetic Resonance) comes in super handy.
Basics of NMR for Chemical Analysis
NMR is like a magic tool for chemists. It helps us peek inside the molecules and figure out what's going on at the atomic level. You see, different atoms in a molecule have different magnetic properties. When we put the sample in a strong magnetic field and zap it with radio waves, the atoms absorb and re - emit energy in a way that's unique to their environment within the molecule. By analyzing these signals, we can piece together the structure of the compound.
1H NMR for CAS 13674 - 84 - 5
One of the most commonly used NMR techniques is 1H NMR, which focuses on hydrogen atoms. In the case of CAS 13674 - 84 - 5, the 1H NMR spectrum can tell us a lot about the types of hydrogen atoms present and their chemical environment.
For example, if there are hydrogen atoms attached to different functional groups like alkyl chains or aromatic rings, they'll show up at different positions on the spectrum. The position of the peaks, called the chemical shift, is measured in parts per million (ppm). Aromatic hydrogens usually show up in the 6 - 8 ppm range, while alkyl hydrogens are typically found between 0 - 3 ppm.
The splitting pattern of the peaks also gives us clues. If a hydrogen atom is next to other hydrogen atoms, its peak will split according to the n + 1 rule. For instance, if a hydrogen is adjacent to 2 other hydrogens, its peak will split into a triplet (2+1). By analyzing these splitting patterns, we can figure out the connectivity of the hydrogen - containing groups in CAS 13674 - 84 - 5.
13C NMR for CAS 13674 - 84 - 5
13C NMR is another great technique. It focuses on carbon atoms. Just like 1H NMR, the chemical shift of carbon atoms in 13C NMR can tell us about the type of carbon and its environment.
Carbon atoms in different functional groups have characteristic chemical shifts. For example, carbonyl carbons (C=O) show up in the 160 - 220 ppm range, while aliphatic carbons are usually in the 0 - 60 ppm range. By looking at the 13C NMR spectrum of CAS 13674 - 84 - 5, we can identify the different types of carbon atoms present in the molecule and get an idea of the overall carbon skeleton.
Heteronuclear NMR Techniques
There are also heteronuclear NMR techniques that involve looking at the interaction between different types of nuclei. One such technique is 31P NMR. Since phosphorus is often a key element in flame - retardant compounds like CAS 13674 - 84 - 5, 31P NMR can provide valuable information.
The 31P NMR spectrum can tell us about the chemical environment of the phosphorus atom in the molecule. The chemical shift of the 31P peak can be affected by factors like the type of groups attached to the phosphorus and the oxidation state of the phosphorus. This information can help us understand the bonding and structure around the phosphorus atom in CAS 13674 - 84 - 5.
2D NMR Techniques
Two - dimensional (2D) NMR techniques are even more powerful. They can help us establish the connectivity between different atoms in the molecule. For example, the COSY (Correlation Spectroscopy) experiment is a 2D 1H - 1H NMR technique. It shows the coupling between different hydrogen atoms in the molecule.
By looking at the cross - peaks in the COSY spectrum, we can figure out which hydrogen atoms are close to each other in the molecule. Another useful 2D technique is HMQC (Heteronuclear Multiple - Quantum Coherence). This technique shows the correlation between hydrogen and carbon atoms. It can help us assign the carbon and hydrogen atoms in the molecule more accurately.
Comparison with Similar Flame - Retardant Compounds
It's also interesting to compare the NMR spectra of CAS 13674 - 84 - 5 with those of other flame - retardant compounds. For example, Tritolyl Phosphate, Tri（2 - chloroisopropyl) Phosphate, and Triethyl Phosphate are all well - known flame - retardants.
By comparing their NMR spectra, we can see the similarities and differences in their structures. This can help us understand the unique properties of CAS 13674 - 84 - 5 and how it might perform compared to these other compounds.
