Rifaximin EP Impurity A CAS 695-34-1

Description

Compared with other compounds in its class, the molecular weight of 108.14 g/mol gives Rifaximin EP Impurity A distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Rifaximin EP Impurity A (CAS 695-34-1, C6H8N2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a nitrile group, an aromatic ring system, Rifaximin EP Impurity A is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 108.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 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.

CATO manufactures Rifaximin EP Impurity A under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
