Description

As a certified reference material (CRM), (E)-4-((4-(Benzylamino)phenyl)diazenyl)benzenesulfonic acid, sodium salt 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.

(E)-4-((4-(Benzylamino)phenyl)diazenyl)benzenesulfonic acid, sodium salt (CAS 36402-77-4) is a high-purity analytical reference standard with the molecular formula C19H16N3NaO3S and a molecular weight of 389.40 g/mol.

Based on its molecular formula C19H16N3NaO3S, (E)-4-((4-(Benzylamino)phenyl)diazenyl)benzenesulfonic acid, sodium salt contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 389.40 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
