Chemical Structure
Description
The occurrence of (S)-2-hydroxy-1,2-diphenylethan-1-one is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-2-hydroxy-1,2-diphenylethan-1-one (CAS 5928-67-6) is a high-purity analytical reference standard with the molecular formula C14H12O2 and a molecular weight of 212.24 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (S)-2-hydroxy-1,2-diphenylethan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 212.24 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.
