Chemical Structure
Description
Structurally, 1,1'-(2,4-Dihydroxy-1,3-phenylene)bis(ethan-1-one) (C10H10O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 194.18 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
1,1'-(2,4-Dihydroxy-1,3-phenylene)bis(ethan-1-one) (CAS 2163-12-4) is a high-purity analytical reference standard with the molecular formula C10H10O4 and a molecular weight of 194.18 g/mol.
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.
