Chemical Structure

Potassium 2-phenylacetate CAS 13005-36-2 chemical structure

Description

CATO supplies Potassium 2-phenylacetate (CAS 13005-36-2), a certified reference material (molecular formula C8H7O2K, MW 174.24 g/mol) for analytical method development and quality control.

Structurally, Potassium 2-phenylacetate (C8H7O2K) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 174.24 g/mol, it falls into the medium-molecular-weight range. 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).

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.
