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.

trans-2-[2-(2-Methoxyphenyl)-2-oxoethyl]-cyclohexane-1-carboxylic acid (CAS 735274-73-4), molecular formula C16H20O4 and molecular weight 276.33 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, trans-2-[2-(2-Methoxyphenyl)-2-oxoethyl]-cyclohexane-1-carboxylic acid (C16H20O4) contains a flavonoid core, a hydroxyl group, an ether linkage. 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 276.33 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).

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.
