Chemical Structure
Description
1-(2-Methyl-5-nitrophenyl)-1H-pyrrole (CAS 94009-16-2) is a high-purity analytical reference standard with the molecular formula C11H10N2O2 and a molecular weight of 202.21 g/mol.
The molecular framework of 1-(2-Methyl-5-nitrophenyl)-1H-pyrrole (C11H10N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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. 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 1-(2-Methyl-5-nitrophenyl)-1H-pyrrole 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.
