(5-(1,3-Dioxolan-2-yl)thiophen-2-yl)(2,3-dichlorophenyl)methanone CAS 898778-86-4

Description

The occurrence of (5-(1,3-Dioxolan-2-yl)thiophen-2-yl)(2,3-dichlorophenyl)methanone is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(5-(1,3-Dioxolan-2-yl)thiophen-2-yl)(2,3-dichlorophenyl)methanone (CAS 898778-86-4), molecular formula C14H10Cl2O3S and molecular weight 329.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, (5-(1,3-Dioxolan-2-yl)thiophen-2-yl)(2,3-dichlorophenyl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
