Description
2-Chloro-4-(trifluoromethyl)pyridine is a halogenated pyridine building block supplied for chemical synthesis and biochemical research. Identified by CAS number 81565-18-6, it has the empirical formula C₆H₃ClF₃N and a molar mass of 181,54 g/mol. The material shows a density of 1,416 g/cm³ and a boiling point of 172,5 °C, supporting predictable handling in organic reaction workflows. The chloro and trifluoromethyl substitution pattern makes the compound relevant for constructing more complex heterocyclic scaffolds in medicinal chemistry and materials-oriented synthesis. Offered from manufacturer Carl ROTH, the reagent integrates readily into standard laboratory inventories for pyridine chemistry. Researchers value clear identity data—CAS, formula, molar mass, density, and boiling point—when planning stoichiometry, solvent choice, and thermal conditions. Use the product under appropriate laboratory controls for halogenated aromatics and fluorinated intermediates. The compact pack supports efficient trial reactions while limiting excess inventory for specialised pyridine derivatives.

Questions about 2-Chloro-4-(trifluoromethyl)pyridine, 5 g
What is this article?
2-Chloro-4-(trifluoromethyl)pyridine, 5 g 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.
