Chemical Structure
Description
(1R,2S)-2-(2,6-dimethylbenzoyl)cyclopentane-1-carboxylic acid (CAS 733740-20-0) is a high-purity analytical reference standard with the molecular formula C15H18O3 and a molecular weight of 246.30 g/mol.
Structurally, (1R,2S)-2-(2,6-dimethylbenzoyl)cyclopentane-1-carboxylic acid (C15H18O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 246.30 g/mol, it falls into the medium-molecular-weight range. 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.
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.
