Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(2-Bromoethyl)-1-chloro-2-fluorobenzene.
4-(2-Bromoethyl)-1-chloro-2-fluorobenzene (CAS 1260790-89-3) is a high-purity analytical reference standard with the molecular formula C8H7BrClF and a molecular weight of 237.50 g/mol.
4-(2-Bromoethyl)-1-chloro-2-fluorobenzene (C8H7BrClF) contains fluorine/chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4-(2-Bromoethyl)-1-chloro-2-fluorobenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
