Phenobarbital Impurity 01 CAS 69125-70-8

Description

Compared with other compounds in its class, the molecular weight of 230.27 g/mol gives Phenobarbital Impurity 01 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Phenobarbital Impurity 01 (CAS 69125-70-8) is a certified pharmaceutical impurity reference standard with the molecular formula C12H14N4O and a molecular weight of 230.27 g/mol.

Phenobarbital Impurity 01 (C12H14N4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

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.
