1-(Bromomethyl)-2-fluoro-5-methyl-3-(trifluoromethyl)benzene CAS 1706438-74-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(Bromomethyl)-2-fluoro-5-methyl-3-(trifluoromethyl)benzene.

1-(Bromomethyl)-2-fluoro-5-methyl-3-(trifluoromethyl)benzene (CAS 1706438-74-5), molecular formula C9H7BrF4 and molecular weight 271.05 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to fluorine/bromine substitution, an aromatic ring system, 1-(Bromomethyl)-2-fluoro-5-methyl-3-(trifluoromethyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 1-(Bromomethyl)-2-fluoro-5-methyl-3-(trifluoromethyl)benzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
