Chemical Structure

4,4'-(Propane-1,3-diylbis(oxy))bis(benzene-1,3-diamine) tetrahydrochloride CAS 74918-21-1 chemical structure

Description

The occurrence of 4,4'-(Propane-1,3-diylbis(oxy))bis(benzene-1,3-diamine) tetrahydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,4'-(Propane-1,3-diylbis(oxy))bis(benzene-1,3-diamine) tetrahydrochloride (CAS 74918-21-1) is a high-purity analytical reference standard with the molecular formula C15H20N4O2HCl and a molecular weight of 324.81 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4,4'-(Propane-1,3-diylbis(oxy))bis(benzene-1,3-diamine) tetrahydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 324.81 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.

As a certified reference material (CRM), 4,4'-(Propane-1,3-diylbis(oxy))bis(benzene-1,3-diamine) tetrahydrochloride 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.
