3,4-Bis(4-methoxyphenyl)-1-[(4-methylphenyl)methyl]-1H-pyrazole CAS 955976-47-3

Description

The occurrence of 3,4-Bis(4-methoxyphenyl)-1-[(4-methylphenyl)methyl]-1H-pyrazole is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,4-Bis(4-methoxyphenyl)-1-[(4-methylphenyl)methyl]-1H-pyrazole (CAS 955976-47-3), molecular formula C25H24N2O2 and molecular weight 384.47 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,4-Bis(4-methoxyphenyl)-1-[(4-methylphenyl)methyl]-1H-pyrazole (C25H24N2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. 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.

As a certified reference material (CRM), 3,4-Bis(4-methoxyphenyl)-1-[(4-methylphenyl)methyl]-1H-pyrazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
