Description
4-Trifluoromethylbiphenyl is a fluorinated biaryl compound identified by CAS number 398-36-7 and the empirical formula C₁₃H₉F₃. With a molar mass of 222,21 g/mol, this aromatic building block combines a biphenyl core with a para-trifluoromethyl substituent, a motif frequently employed in modern organic and medicinal chemistry. The electron-withdrawing CF₃ group modulates polarity, metabolic stability and intermolecular interactions, making the molecule useful for cross-coupling studies, ligand design and the synthesis of more elaborate fluorinated scaffolds. Laboratories focused on agrochemical, pharmaceutical or materials research can use the defined CAS identity and molecular formula for accurate stoichiometry and documentation. The compact unit quantity supports efficient screening and method development while limiting excess inventory. Consistent specification of molar mass and structure enables straightforward integration into electronic laboratory notebooks and regulatory or quality-control records based solely on the manufacturer’s stated data.

Questions about 4-Trifluoromethylbiphenyl, 500 mg
What is this article?
4-Trifluoromethylbiphenyl, 500 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Photometers & spectrophotometers, inside Spectroscopy & photometry, in Lab instruments.
A photometer reads absorbance at one or a few wavelengths. A spectrophotometer scans or selects many. Both send light through a cuvette or a well. The wavelength range, UV or visible, and the bandwidth decide what can be measured. A visible-only instrument cannot read a nucleic acid at 260 nm.
A photometer or spectrophotometer sends light through a sample and reads how much was absorbed. In the range where the Beer–Lambert relation holds, absorbance tracks concentration. A refractometer reads how a liquid bends light, which tracks dissolved solids. A polarimeter reads the rotation of polarised light, the classical measurement for sugars. The lamp, the wavelength and the cuvette path length are the three things that have to be right before the number means anything. The optical quantities trace to NIST and the BIPM.
