Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6420-90-2 2-(4-Hydroxyphenyl)-1-phenylethan-1-one DTXSID00540496 (CAS 6420-90-2), molecular formula C14H12O2 and molecular weight 212.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6420-90-2 2-(4-Hydroxyphenyl)-1-phenylethan-1-one DTXSID00540496 (C14H12O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
