Chemical Structure

Rifampicin CAS 13292-46-1 chemical structure

Description

Rifampicin (CAS 13292-46-1) is a high-purity analytical reference standard with the molecular formula C43H58N4O12 and a molecular weight of 822.94 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Rifampicin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 822.94 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures Rifampicin 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.
