Description

The occurrence of rac-(1R,2R)-2-(2,5-dimethoxyphenyl)cyclopropane-1-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies rac-(1R,2R)-2-(2,5-dimethoxyphenyl)cyclopropane-1-carboxylic acid (CAS 1430328-71-4), a certified reference material (molecular formula C12H14O4, MW 222.24 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H14O4, rac-(1R,2R)-2-(2,5-dimethoxyphenyl)cyclopropane-1-carboxylic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 222.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
