2243-83-6 2-Naphthoyl chloride 2-Naphthalenecarbonyl chloride 2-(Chlorocarbonyl)naphthalene EINECS 218-822-5 beta-Naphthalenecarbonyl chloride 2-Naphthoic chloride beta-Naphthoyl chloride NSC 9842 CAS 2243-83-6

Description

Structurally, 2243-83-6 2-Naphthoyl chloride 2-Naphthalenecarbonyl chloride 2-(Chlorocarbonyl)naphthalene EINECS 218-822-5 beta-Naphthalenecarbonyl chloride 2-Naphthoic chloride beta-Naphthoyl chloride NSC 9842 (C11H17ClO) contains a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 200.71 g/mol, it falls into the medium-molecular-weight range. 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).

2243-83-6 2-Naphthoyl chloride 2-Naphthalenecarbonyl chloride 2-(Chlorocarbonyl)naphthalene EINECS 218-822-5 beta-Naphthalenecarbonyl chloride 2-Naphthoic chloride beta-Naphthoyl chloride NSC 9842 (CAS 2243-83-6) is a high-purity analytical reference standard with the molecular formula C11H17ClO and a molecular weight of 200.71 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
