Chemical Structure
Description
3-(3,5-Dimethyl-1H-pyrazol-4-yl)-4-methylmorpholine (CAS 2093509-75-0), molecular formula C10H17N3O and molecular weight 195.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(3,5-Dimethyl-1H-pyrazol-4-yl)-4-methylmorpholine (C10H17N3O) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
