Chemical Structure

ethyl 5-(4-(4-(3,5-dimethylisoxazole-4-carbonyl)piperazin-1-yl)phenyl)-1-(3-fluorophenyl)-1H-pyrazole-3-carboxylate CAS 1007477-89-5 chemical structure

Description

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, ethyl 5-(4-(4-(3,5-dimethylisoxazole-4-carbonyl)piperazin-1-yl)phenyl)-1-(3-fluorophenyl)-1H-pyrazole-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 517.55 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).

ethyl 5-(4-(4-(3,5-dimethylisoxazole-4-carbonyl)piperazin-1-yl)phenyl)-1-(3-fluorophenyl)-1H-pyrazole-3-carboxylate (CAS 1007477-89-5) is a high-purity analytical reference standard with the molecular formula C28H28FN5O4 and a molecular weight of 517.55 g/mol.

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.
