2-(4-tert-Butylphenyl)cyclopropane-1-carboxylic acid CAS 445029-32-3

Description

Compared with other compounds in its class, the molecular weight of 218.29 g/mol gives 2-(4-tert-Butylphenyl)cyclopropane-1-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(4-tert-Butylphenyl)cyclopropane-1-carboxylic acid (CAS 445029-32-3), molecular formula C14H18O2 and molecular weight 218.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-(4-tert-Butylphenyl)cyclopropane-1-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.29 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.
