Chemical Structure

Pregnenolone-d4 CAS 61574-54-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 320.50 g/mol gives Pregnenolone-d4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Pregnenolone-d4 (CAS 61574-54-7), molecular formula C21H28D4O2 and molecular weight 320.50 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C21H28D4O2, Pregnenolone-d4 contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 320.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
