U-44069 CAS 56985-32-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 350.49 g/mol gives U-44069 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies U-44069 (CAS 56985-32-1), a certified reference material (molecular formula C21H34O4, MW 350.49 g/mol) for analytical method development and quality control.

Based on its molecular formula C21H34O4, U-44069 contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 350.49 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
