Chemical Structure
Description
Pyrrolo[2,1,5-cd]indolizine (CAS 209-81-4) is a high-purity analytical reference standard with the molecular formula C10H6Cl2 and a molecular weight of 197.06 g/mol.
Pyrrolo[2,1,5-cd]indolizine (C10H6Cl2) contains chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Pyrrolo[2,1,5-cd]indolizine 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.
