Description
As a certified reference material (CRM), N-(2,4-Dichlorophenyl)-3,4-dihydro-2H-pyrrol-5-amine 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.
N-(2,4-Dichlorophenyl)-3,4-dihydro-2H-pyrrol-5-amine (CAS 51170-87-7) is a high-purity analytical reference standard with the molecular formula C10H10Cl2N2 and a molecular weight of 229.11 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, N-(2,4-Dichlorophenyl)-3,4-dihydro-2H-pyrrol-5-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
