1-(3-Chlorophenyl)naphthalene CAS 7731-48-8 chemical structure

Description

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.

CATO supplies 1-(3-Chlorophenyl)naphthalene (CAS 7731-48-8), a certified reference material (molecular formula C16H11Cl, MW 238.71 g/mol) for analytical method development and quality control.

Based on its molecular formula C16H11Cl, 1-(3-Chlorophenyl)naphthalene contains chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 238.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
