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.
CATO supplies 1-(Methyl-D3)-4-nitro-3-propyl-1H-pyrazole-5-carboxylic Acid (CAS 526203-29-2), a certified reference material (molecular formula C8H8D3N3O4, MW 216.21 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H8D3N3O4, 1-(Methyl-D3)-4-nitro-3-propyl-1H-pyrazole-5-carboxylic Acid contains deuterium isotope labeling, an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 216.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
