1,3,3-Trimethyl-2',5'-diphenyl-2',4'-dihydrospiro[indoline-2,3'-pyrazole] CAS 72619-75-1

Description

Compared with other compounds in its class, the molecular weight of 367.49 g/mol gives 1,3,3-Trimethyl-2',5'-diphenyl-2',4'-dihydrospiro[indoline-2,3'-pyrazole] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,3,3-Trimethyl-2',5'-diphenyl-2',4'-dihydrospiro[indoline-2,3'-pyrazole] (CAS 72619-75-1) is a high-purity analytical reference standard with the molecular formula C25H25N3 and a molecular weight of 367.49 g/mol.

1,3,3-Trimethyl-2',5'-diphenyl-2',4'-dihydrospiro[indoline-2,3'-pyrazole] (C25H25N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
