Chemical Structure

Famciclovir USP Related Compound C CAS 174155-70-5 chemical structure

Description

The occurrence of Famciclovir USP Related Compound C 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.

CATO supplies Famciclovir USP Related Compound C (CAS 174155-70-5), a pharmacopoeial impurity reference standard (molecular formula C12H17N5O2, MW 263.30 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Famciclovir USP Related Compound C (C12H17N5O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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.

As a certified reference material (CRM), Famciclovir USP Related Compound C meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
