Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Bromo-3-phenylbicyclo[1.1.1]Pentane.
1-Bromo-3-phenylbicyclo[1.1.1]Pentane (CAS 112043-92-2) is a high-purity analytical reference standard with the molecular formula C11H11Br and a molecular weight of 223.11 g/mol.
Owing to bromine substitution, an aromatic ring system, 1-Bromo-3-phenylbicyclo[1.1.1]Pentane is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 223.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
