Chemical Structure

1,1-Bis(2-chloroethyl)-2-((5-nitrofuran-2-yl)methylene)hydrazine CAS 19819-37-5 chemical structure

Description

1,1-Bis(2-chloroethyl)-2-((5-nitrofuran-2-yl)methylene)hydrazine (CAS 19819-37-5) is a high-purity analytical reference standard with the molecular formula C9H11Cl2N3O3 and a molecular weight of 280.11 g/mol.

Based on its molecular formula C9H11Cl2N3O3, 1,1-Bis(2-chloroethyl)-2-((5-nitrofuran-2-yl)methylene)hydrazine contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 280.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 1,1-Bis(2-chloroethyl)-2-((5-nitrofuran-2-yl)methylene)hydrazine 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.
