NINGBO INNO PHARMCHEM CO.,LTD. ensures the high quality of its 3,4-Dibromotoluene, supporting rigorous scientific investigation.

Spectroscopic methods provide a detailed molecular fingerprint for 3,4-Dibromotoluene. Nuclear Magnetic Resonance (NMR) spectroscopy is paramount. The ¹H NMR spectrum clearly shows the signals for the methyl protons and the distinct aromatic proton resonances, whose chemical shifts and coupling patterns are dictated by the substituent pattern. ¹³C NMR complements this by identifying the different carbon environments. Mass spectrometry (MS) is crucial for confirming the molecular weight, with the characteristic isotopic cluster for dibrominated compounds serving as a key identifier. High-resolution MS can further verify the elemental composition. Raman spectroscopy offers additional vibrational information, providing spectral fingerprints that can differentiate between isomers.

Computational chemistry plays an equally significant role in understanding 3,4-Dibromotoluene. Techniques such as Density Functional Theory (DFT) allow for the prediction of molecular geometries, optimized structures, and spectroscopic properties, which can be correlated with experimental data. These calculations are also vital for elucidating reaction mechanisms. By modeling transition states and intermediates, DFT can predict the regioselectivity of reactions involving 3,4-Dibromotoluene, offering explanations for experimental observations, such as the non-regioselective outcomes in certain copper-catalyzed annulation reactions.

The interplay between experimental spectroscopy and theoretical computation is critical. For instance, computed NMR chemical shifts can aid in assigning the complex aromatic proton signals in the ¹H NMR spectrum. Similarly, predicted vibrational frequencies can help in interpreting Raman spectra. This integrated approach not only confirms the identity and purity of 3,4-Dibromotoluene but also provides deeper mechanistic understanding. NINGBO INNO PHARMCHEM CO.,LTD. supports this scientific endeavor by providing high-purity 3,4-Dibromotoluene, enabling detailed spectroscopic and computational studies that advance chemical knowledge and applications.

By leveraging these analytical and computational tools, scientists can fully harness the synthetic potential of 3,4-Dibromotoluene, paving the way for new discoveries in chemistry and related fields.
