Famotidine impurity HCl, >98% CAS 100599-91-5

Description

Compared with other compounds in its class, the molecular weight of 192.66 g/mol gives Famotidine impurity HCl, >98% distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Famotidine impurity HCl, >98% (CAS 100599-91-5), molecular formula C5H8N4SHCl and molecular weight 192.66 g/mol, is a CATO reference standard with documented purity and traceability.

Famotidine impurity HCl, >98% (C5H8N4SHCl) contains a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
