4-Chloro-6-hydroxy-2,3-dihydro-1H-inden-1-one CAS 1199782-98-3

Description

The occurrence of 4-Chloro-6-hydroxy-2,3-dihydro-1H-inden-1-one is closely related to 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.

4-Chloro-6-hydroxy-2,3-dihydro-1H-inden-1-one (CAS 1199782-98-3) is a high-purity analytical reference standard with the molecular formula C9H7ClO2 and a molecular weight of 182.60 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 4-Chloro-6-hydroxy-2,3-dihydro-1H-inden-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.60 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.

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.
