Chemical Structure

potassium 5-hydroxy-5-phenylpentanoate CAS 1909310-11-7 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, potassium 5-hydroxy-5-phenylpentanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

potassium 5-hydroxy-5-phenylpentanoate (CAS 1909310-11-7), molecular formula C11H13O3K and molecular weight 232.32 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
