Chemical Structure
Description
The molecular framework of 6-((2,3-Dimethylphenyl)carbamoyl)cyclohex-3-ene-1-carboxylic acid (C16H19NO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
6-((2,3-Dimethylphenyl)carbamoyl)cyclohex-3-ene-1-carboxylic acid (CAS 198283-88-4) is a high-purity analytical reference standard with the molecular formula C16H19NO3 and a molecular weight of 273.33 g/mol.
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.
