Description

Compared with other compounds in its class, the molecular weight of 266.34 g/mol gives 1-(3,5-diphenylpyrazolidin-1-yl)ethanone 1-Acetyl-3,5-diphenylpyrazolidine 332102-25-7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(3,5-diphenylpyrazolidin-1-yl)ethanone 1-Acetyl-3,5-diphenylpyrazolidine 332102-25-7 (CAS 332102-25-7), molecular formula C17H18N2O and molecular weight 266.34 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1-(3,5-diphenylpyrazolidin-1-yl)ethanone 1-Acetyl-3,5-diphenylpyrazolidine 332102-25-7 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 266.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
