Chemical Structure

(1R,3S)-3-(2-oxo-2-(p-tolyl)ethyl)cyclohexane-1-carboxylic acid CAS 735275-07-7 chemical structure

Description

The occurrence of (1R,3S)-3-(2-oxo-2-(p-tolyl)ethyl)cyclohexane-1-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(1R,3S)-3-(2-oxo-2-(p-tolyl)ethyl)cyclohexane-1-carboxylic acid (CAS 735275-07-7) is a high-purity analytical reference standard with the molecular formula C16H20O3 and a molecular weight of 260.33 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (1R,3S)-3-(2-oxo-2-(p-tolyl)ethyl)cyclohexane-1-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
