Description

The occurrence of 28900-27-8 spectinabilin neoaureothin 2-methoxy-3,5-dimethyl-6-{(2R,4Z)-4-[(2E,4E,6E)-2,4,6-trimethyl-7-(4-nitrophenyl)hepta-2,4,6-trien-1-ylidene]tetrahydrofuran-2-yl}-4H-pyran-4-one (+)-spectinabilin (+)-neoaureothin CHEBI:142841 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 28900-27-8 spectinabilin neoaureothin 2-methoxy-3,5-dimethyl-6-{(2R,4Z)-4-[(2E,4E,6E)-2,4,6-trimethyl-7-(4-nitrophenyl)hepta-2,4,6-trien-1-ylidene]tetrahydrofuran-2-yl}-4H-pyran-4-one (+)-spectinabilin (+)-neoaureothin CHEBI:142841 (CAS 28900-27-8), a certified reference material (molecular formula C28H31NO6, MW 477.55 g/mol) for analytical method development and quality control.

Based on its molecular formula C28H31NO6, 28900-27-8 spectinabilin neoaureothin 2-methoxy-3,5-dimethyl-6-{(2R,4Z)-4-[(2E,4E,6E)-2,4,6-trimethyl-7-(4-nitrophenyl)hepta-2,4,6-trien-1-ylidene]tetrahydrofuran-2-yl}-4H-pyran-4-one (+)-spectinabilin (+)-neoaureothin CHEBI:142841 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 477.55 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.
