1-(2-Bromo-1-cyclobutoxyethyl)-2-fluorobenzene CAS 1249524-85-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Bromo-1-cyclobutoxyethyl)-2-fluorobenzene.

1-(2-Bromo-1-cyclobutoxyethyl)-2-fluorobenzene (CAS 1249524-85-3), molecular formula C12H14BrFO and molecular weight 273.14 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 1-(2-Bromo-1-cyclobutoxyethyl)-2-fluorobenzene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 273.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
