Picosulfate impurity 28 CAS 2379878-04-1

Description

Compared with other compounds in its class, the molecular weight of 453.44 g/mol gives Picosulfate impurity 28 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Picosulfate impurity 28 (CAS 2379878-04-1) is a certified pharmaceutical impurity reference standard with the molecular formula C18H15NO9S2 and a molecular weight of 453.44 g/mol.

Structurally, Picosulfate impurity 28 (C18H15NO9S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 453.44 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
