Chemical Structure

Lactitol Impurity 3 CAS 96130-71-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 306.27 g/mol gives Lactitol Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Lactitol Impurity 3 (CAS 96130-71-1), a pharmacopoeial impurity reference standard (molecular formula C12H18O9, MW 306.27 g/mol) used for the identification and quantification of trace impurities in APIs.

Lactitol Impurity 3 (C12H18O9) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
