Chemical Structure

2-Cycloheptylacetic acid CAS 4401-20-1 chemical structure

Description

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.

2-Cycloheptylacetic acid (CAS 4401-20-1) is a high-purity analytical reference standard with the molecular formula C9H16O2 and a molecular weight of 156.22 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Cycloheptylacetic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 156.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
