Polidocanol Impurity 3 (Polidocanol E12) CAS 3056-00-6

Description

Compared with other compounds in its class, the molecular weight of 714.96 g/mol gives Polidocanol Impurity 3 (Polidocanol E12) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Polidocanol Impurity 3 (Polidocanol E12) (CAS 3056-00-6), a pharmacopoeial impurity reference standard (molecular formula C36H74O13, MW 714.96 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, Polidocanol Impurity 3 (Polidocanol E12) is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 714.96 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
