Chemical Structure
Description
The occurrence of Furazolidone Impurity 2 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Furazolidone Impurity 2 (CAS CATO-C4X-29012) is a certified pharmaceutical impurity reference standard with the molecular formula C5H10N2O3 and a molecular weight of 146.14 g/mol.
Structurally, Furazolidone Impurity 2 (C5H10N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 146.14 g/mol, it falls into the low-molecular-weight range. 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.
