Chemical Structure

(3-Phenyl-1-(m-tolyl)-1H-pyrazol-4-yl)methanol CAS 618441-86-4 chemical structure

Description

(3-Phenyl-1-(m-tolyl)-1H-pyrazol-4-yl)methanol (CAS 618441-86-4), molecular formula C17H16N2O and molecular weight 264.32 g/mol, is a CATO reference standard with documented purity and traceability.

(3-Phenyl-1-(m-tolyl)-1H-pyrazol-4-yl)methanol (C17H16N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.
