Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-(2,4-Dichlorophenyl)-1H-pyrrole-2-carbaldehyde (CAS 708288-96-4), molecular formula C11H7Cl2NO and molecular weight 240.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(2,4-Dichlorophenyl)-1H-pyrrole-2-carbaldehyde (C11H7Cl2NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 5-(2,4-Dichlorophenyl)-1H-pyrrole-2-carbaldehyde 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.
