1H-Pyrazole-4-carboxaldehyde,3-dihydro-1,5-dimethyl-3-oxo-2-phenyl- 4-Antipyrinecarboxaldehyde 4-Formylantipyrine 950-81-2 Antipyraldehyde Antipyrinaldehyd Antipyrine, 4-formyl- Febranine NSC-60408 NSC60408 (CAS 950-81-2) is a high-purity analytical reference standard with the molecular formula C12H18N2O2 and a molecular weight of 222.28 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1H-Pyrazole-4-carboxaldehyde,3-dihydro-1,5-dimethyl-3-oxo-2-phenyl- 4-Antipyrinecarboxaldehyde 4-Formylantipyrine 950-81-2 Antipyraldehyde Antipyrinaldehyd Antipyrine, 4-formyl- Febranine NSC-60408 NSC60408 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
