Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diosmin Impurity 9.
CATO supplies Diosmin Impurity 9 (CAS 3070516-52-5), a pharmacopoeial impurity reference standard (molecular formula C28H31IO15, MW 734.44 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, a polycyclic aromatic system, Diosmin Impurity 9 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 734.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
