Chemical Structure
Description
(2,5-Dimethoxyphenyl)(pyridin-2-yl)methanone (CAS 64306-56-5), molecular formula C14H13NO3 and molecular weight 243.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2,5-Dimethoxyphenyl)(pyridin-2-yl)methanone (C14H13NO3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
