Famotidine Impurity 11 CAS 128648-99-7 chemical structure

Description

Famotidine Impurity 11 (CAS 128648-99-7) is a high-purity analytical reference standard with the molecular formula C3H8N2O and a molecular weight of 88.11 g/mol.

Famotidine Impurity 11 (C3H8N2O) contains 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
