2-(2-Isopropyl-5-methylphenoxy)-2-methylpropanoic acid CAS 97283-84-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-Isopropyl-5-methylphenoxy)-2-methylpropanoic acid.

2-(2-Isopropyl-5-methylphenoxy)-2-methylpropanoic acid (CAS 97283-84-6) is a high-purity analytical reference standard with the molecular formula C14H20O3 and a molecular weight of 236.31 g/mol.

The molecular framework of 2-(2-Isopropyl-5-methylphenoxy)-2-methylpropanoic acid (C14H20O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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).

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.
