3'-Chlorophenyl acetylene 1-chloro-3-ethynylbenzene 1-chloro-3-ethynyl-benzene 3-chloro-1-ethynylbenzene 3-chlorophenylacetylene 3'-chlorophenylacetylene 766-83-6 CAS 766-83-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3'-Chlorophenyl acetylene 1-chloro-3-ethynylbenzene 1-chloro-3-ethynyl-benzene 3-chloro-1-ethynylbenzene 3-chlorophenylacetylene 3'-chlorophenylacetylene 766-83-6.

3'-Chlorophenyl acetylene 1-chloro-3-ethynylbenzene 1-chloro-3-ethynyl-benzene 3-chloro-1-ethynylbenzene 3-chlorophenylacetylene 3'-chlorophenylacetylene 766-83-6 (CAS 766-83-6) is a high-purity analytical reference standard with the molecular formula C8H11Cl and a molecular weight of 142.63 g/mol.

Owing to chlorine substitution, 3'-Chlorophenyl acetylene 1-chloro-3-ethynylbenzene 1-chloro-3-ethynyl-benzene 3-chloro-1-ethynylbenzene 3-chlorophenylacetylene 3'-chlorophenylacetylene 766-83-6 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.63 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.
