Chemical Structure
Description
898771-24-9 (2-Chlorophenyl)(thiophen-3-yl)methanone DTXSID40591669 (CAS 898771-24-9), molecular formula C11H7ClOS and molecular weight 222.69 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 898771-24-9 (2-Chlorophenyl)(thiophen-3-yl)methanone DTXSID40591669 (C11H7ClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 222.69 g/mol, it falls into the medium-molecular-weight range. 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.
