Chemical Structure
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.
Methyl 3-cyclohexyl-2-[(3-nitropyridin-2-yl)amino]propanoate (CAS 318949-40-5), molecular formula C15H21N3O4 and molecular weight 307.34 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Methyl 3-cyclohexyl-2-[(3-nitropyridin-2-yl)amino]propanoate (C15H21N3O4) contains a flavonoid core, an amide group, 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 307.34 g/mol, it falls into the moderately-high-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.
