Chemical Structure

1,2-Dihydroacenaphthylene-5-sulfonyl Chloride CAS 17070-55-2 chemical structure

Description

The occurrence of 1,2-Dihydroacenaphthylene-5-sulfonyl Chloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1,2-Dihydroacenaphthylene-5-sulfonyl Chloride (CAS 17070-55-2), a certified reference material (molecular formula C12H9ClO2S, MW 252.72 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H9ClO2S, 1,2-Dihydroacenaphthylene-5-sulfonyl Chloride contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 252.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
