Chemical Structure

2-(2,3-Dihydro-1H-inden-5-yl)-2-oxoacetaldehyde CAS 10188-66-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 174.20 g/mol gives 2-(2,3-Dihydro-1H-inden-5-yl)-2-oxoacetaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(2,3-Dihydro-1H-inden-5-yl)-2-oxoacetaldehyde (CAS 10188-66-6), molecular formula C11H10O2 and molecular weight 174.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-(2,3-Dihydro-1H-inden-5-yl)-2-oxoacetaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
