Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 525.04 g/mol gives 5H-Pyrrolo[3,2-c:4,5-c']dipyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5H-Pyrrolo[3,2-c:4,5-c']dipyridine (CAS 244-78-0) is a high-purity analytical reference standard with the molecular formula C27H31ClN2OC2H2O4 and a molecular weight of 525.04 g/mol.
The molecular framework of 5H-Pyrrolo[3,2-c:4,5-c']dipyridine (C27H31ClN2OC2H2O4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
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 5H-Pyrrolo[3,2-c:4,5-c']dipyridine 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.
