Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 2-Amino-1-(5-bromo-2-methylphenyl)-4,5-dimethyl-1H-pyrrole-3-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.19 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.
2-Amino-1-(5-bromo-2-methylphenyl)-4,5-dimethyl-1H-pyrrole-3-carbonitrile (CAS 1157773-87-9) is a high-purity analytical reference standard with the molecular formula C14H14BrN3 and a molecular weight of 304.19 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Amino-1-(5-bromo-2-methylphenyl)-4,5-dimethyl-1H-pyrrole-3-carbonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
