Chemical Structure

2-[3-(propan-2-yl)phenyl]acetic acid CAS 81049-21-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[3-(propan-2-yl)phenyl]acetic acid.

2-[3-(propan-2-yl)phenyl]acetic acid (CAS 81049-21-0) is a high-purity analytical reference standard with the molecular formula C11H14O2 and a molecular weight of 178.23 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-[3-(propan-2-yl)phenyl]acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
