2-Hydroxy-5-(2-(4-hydroxyphenyl)propan-2-yl)benzoic acid CAS 101949-49-9

Description

Compared with other compounds in its class, the molecular weight of 272.30 g/mol gives 2-Hydroxy-5-(2-(4-hydroxyphenyl)propan-2-yl)benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Hydroxy-5-(2-(4-hydroxyphenyl)propan-2-yl)benzoic acid (CAS 101949-49-9) is a high-purity analytical reference standard with the molecular formula C16H16O4 and a molecular weight of 272.30 g/mol.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 2-Hydroxy-5-(2-(4-hydroxyphenyl)propan-2-yl)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 272.30 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).

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.
