Accurate characterization of chemical compounds is fundamental to their successful application in research and industry. 4-Bromophenetole (CAS 588-96-5), a versatile organic intermediate, requires precise analytical techniques to confirm its identity, purity, and structure. NINGBO INNO PHARMCHEM CO.,LTD. employs a suite of modern spectroscopic methods to ensure the quality and consistency of our 4-Bromophenetole product, providing our clients with reliable data.

Nuclear Magnetic Resonance (NMR) spectroscopy is indispensable for elucidating the molecular structure of 4-Bromophenetole. Proton NMR (¹H NMR) provides detailed information about the hydrogen atoms within the molecule, revealing characteristic signals for the aromatic protons and the ethyl group. The spectrum typically shows two distinct doublets for the aromatic protons due to their differing electronic environments relative to the bromine and ethoxy substituents, along with a quartet and a triplet corresponding to the methylene and methyl protons of the ethyl group, respectively. Carbon-13 NMR (¹³C NMR) further complements this by mapping the carbon skeleton, identifying unique signals for each carbon atom, including those attached to bromine and oxygen.

Mass Spectrometry (MS) is another powerful tool for identifying 4-Bromophenetole. High-Resolution Mass Spectrometry (HRMS) can determine the exact mass of the molecular ion, allowing for the confirmation of its elemental formula (C8H9BrO). The mass spectrum of 4-Bromophenetole exhibits a characteristic isotopic pattern due to the presence of bromine, with peaks at m/z 200 and 202 for the molecular ion. Analysis of fragmentation patterns, such as the loss of an ethyl radical or ethylene molecule, provides further corroboration of its structure.

Infrared (IR) spectroscopy is utilized to identify the key functional groups present in 4-Bromophenetole. The IR spectrum displays characteristic absorption bands for the aromatic C-H stretching vibrations, the C-O-C stretching of the ether linkage, and the C-Br stretching vibration. These specific absorption frequencies help confirm the presence of the expected functional groups, contributing to the overall structural validation.

NINGBO INNO PHARMCHEM CO.,LTD. leverages these advanced analytical techniques to provide comprehensive characterization data for 4-Bromophenetole. This commitment to analytical rigor ensures that our clients receive a product of the highest quality, enabling confident use in their research and development activities across pharmaceuticals, agrochemicals, and materials science.
