Chemical Structure

Probucol Impurity 13 CAS 40084-31-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 332.22 g/mol gives Probucol Impurity 13 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Probucol Impurity 13 (CAS 40084-31-9), a pharmacopoeial impurity reference standard (molecular formula C14H21IO, MW 332.22 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Probucol Impurity 13 (C14H21IO) contains a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 332.22 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
