Dexamethasone Impurity 715 Disodium Salt CAS 39005-10-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dexamethasone Impurity 715 Disodium Salt.

CATO supplies Dexamethasone Impurity 715 Disodium Salt (CAS 39005-10-2), a pharmacopoeial impurity reference standard (molecular formula C22H32FO11PS2Na, MW 609.57 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Dexamethasone Impurity 715 Disodium Salt (C22H32FO11PS2Na) contains a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 609.57 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
