Chemical Structure
Description
1-(3-Bromophenyl)-2,5-dimethyl-1H-pyrrole (CAS 127257-87-8) is a high-purity analytical reference standard with the molecular formula C12H12BrN and a molecular weight of 250.13 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 1-(3-Bromophenyl)-2,5-dimethyl-1H-pyrrole is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 250.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(3-Bromophenyl)-2,5-dimethyl-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.
