Description
4-(Difluoromethyl)benzyl bromide is an organofluorine building block with CAS number 873373-34-3 and empirical formula C₈H₇BrF₂. Its molar mass is 221,04 g/mol, supporting stoichiometric planning in synthetic organic chemistry. The compact unit quantity suits small-scale reactions, method scouting, and controlled addition steps. Classification under UN number 3261 reflects its hazardous-goods handling profile; users should apply appropriate containment and personal protective measures. Physical handling benefits from the small net weight of 0,001 kg, which simplifies storage organisation in refrigerated chemical inventories. This compound is offered from manufacturer Carl ROTH within the chemicals and biochemicals assortment for research environments that need clearly specified halogenated aromatics. Integrate into validated synthetic routes only after reviewing institutional safety guidance for reactive benzyl bromides and fluorinated organics.

Questions about 4-(Difluoromethyl)benzyl bromide, 500 mg
What is this article?
4-(Difluoromethyl)benzyl bromide, 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.
Which category should I open next?
