Description
879-18-5 1-Naphthalenecarbonyl chloride 1-Naphthoyl chloride 1-(Chlorocarbonyl)naphthalene EINECS 212-903-9 1-Naphthoic acid chloride alpha-Naphthoyl chloride NSC 9841 (CAS 879-18-5) is a high-purity analytical reference standard with the molecular formula C11H17ClO and a molecular weight of 200.71 g/mol.
The molecular framework of 879-18-5 1-Naphthalenecarbonyl chloride 1-Naphthoyl chloride 1-(Chlorocarbonyl)naphthalene EINECS 212-903-9 1-Naphthoic acid chloride alpha-Naphthoyl chloride NSC 9841 (C11H17ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
