3-(o-Tolyl)-4,5-dihydro-1H-pyrazole CAS 361442-92-4

Description

Compared with other compounds in its class, the molecular weight of 160.22 g/mol gives 3-(o-Tolyl)-4,5-dihydro-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(o-Tolyl)-4,5-dihydro-1H-pyrazole (CAS 361442-92-4) is a high-purity analytical reference standard with the molecular formula C10H12N2 and a molecular weight of 160.22 g/mol.

The molecular framework of 3-(o-Tolyl)-4,5-dihydro-1H-pyrazole (C10H12N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
