Probucol Impurity 10 CAS 3957-71-9

Description

Compared with other compounds in its class, the molecular weight of 263.40 g/mol gives Probucol Impurity 10 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Probucol Impurity 10 (CAS 3957-71-9) is a certified pharmaceutical impurity reference standard with the molecular formula C15H21NOS and a molecular weight of 263.40 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, Probucol Impurity 10 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 263.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
