Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 510.62 g/mol gives Betamethasone Dipropionate-d6 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Betamethasone Dipropionate-d6 (CAS CATO-C4X-1437107), molecular formula C28H31D6FO7 and molecular weight 510.62 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Betamethasone Dipropionate-d6 (C28H31D6FO7) is characterized by deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
