CATO supplies 1172738-94-1 3-(2-Furyl)-1-(2-oxopropyl)-1H-pyrazole-5-carboxylic acid MFCD14281692 (CAS 1172738-94-1), a certified reference material (molecular formula C11H10N2O4, MW 234.21 g/mol) for analytical method development and quality control.
Structurally, 1172738-94-1 3-(2-Furyl)-1-(2-oxopropyl)-1H-pyrazole-5-carboxylic acid MFCD14281692 (C11H10N2O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 234.21 g/mol, it falls into the medium-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).
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.
