Chemical Structure

Nebramine Impurity N1 CAS 1981-49-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 266.04 g/mol gives Nebramine Impurity N1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Nebramine Impurity N1 (CAS 1981-49-3, C3H8O10P2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Nebramine Impurity N1 (C3H8O10P2) contains a phosphate ester group, a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
