Chemical Structure
Description
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.
1-(3,5-Dimethyl-1H-pyrazol-4-yl)-N-methylethan-1-amine oxalate (CAS 1260743-48-3), molecular formula C8H15N3C2H2O4 and molecular weight 243.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(3,5-Dimethyl-1H-pyrazol-4-yl)-N-methylethan-1-amine oxalate (C8H15N3C2H2O4) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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.
