Chemical Structure

2-(methoxycarbonyl)cyclopentane-1-carboxylic acid CAS 98168-34-4 chemical structure

Description

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.

2-(methoxycarbonyl)cyclopentane-1-carboxylic acid (CAS 98168-34-4) is a high-purity analytical reference standard with the molecular formula C8H12O4 and a molecular weight of 172.18 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-(methoxycarbonyl)cyclopentane-1-carboxylic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
