4'-Bromophenyl acetylene 1-Bromo-4-ethynylbenzene 4-bromophenylacetylene (4-bromophenyl)acetylene 766-96-1 CAS 766-96-1

Description

Compared with other compounds in its class, the molecular weight of 187.08 g/mol gives 4'-Bromophenyl acetylene 1-Bromo-4-ethynylbenzene 4-bromophenylacetylene (4-bromophenyl)acetylene 766-96-1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4'-Bromophenyl acetylene 1-Bromo-4-ethynylbenzene 4-bromophenylacetylene (4-bromophenyl)acetylene 766-96-1 (CAS 766-96-1) is a high-purity analytical reference standard with the molecular formula C8H11Br and a molecular weight of 187.08 g/mol.

Owing to bromine substitution, 4'-Bromophenyl acetylene 1-Bromo-4-ethynylbenzene 4-bromophenylacetylene (4-bromophenyl)acetylene 766-96-1 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 187.08 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.
