Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2 - Chloro - 5 - (trifluoromethyl)benzyl bromide 2-(bromomethyl)-1-chloro-4-(trifluoromethyl)benzene 2-Bromomethyl-1-chloro-4-trifluoromethyl-benzene 237761-77-2 benzene, 2-(bromomethyl)-1-chloro-4-(trifluoromethyl)-.
2 - Chloro - 5 - (trifluoromethyl)benzyl bromide 2-(bromomethyl)-1-chloro-4-(trifluoromethyl)benzene 2-Bromomethyl-1-chloro-4-trifluoromethyl-benzene 237761-77-2 benzene, 2-(bromomethyl)-1-chloro-4-(trifluoromethyl)- (CAS 237761-77-2), molecular formula C8H5BrClF3 and molecular weight 273.48 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H5BrClF3, 2 - Chloro - 5 - (trifluoromethyl)benzyl bromide 2-(bromomethyl)-1-chloro-4-(trifluoromethyl)benzene 2-Bromomethyl-1-chloro-4-trifluoromethyl-benzene 237761-77-2 benzene, 2-(bromomethyl)-1-chloro-4-(trifluoromethyl)- contains fluorine/chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 273.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
