4-Ethoxybenzene-1,2-diamine sulfate CAS 85137-09-3

Description

Compared with other compounds in its class, the molecular weight of 250.27 g/mol gives 4-Ethoxybenzene-1,2-diamine sulfate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Ethoxybenzene-1,2-diamine sulfate (CAS 85137-09-3), a certified reference material (molecular formula C8H12N2OH2O4S, MW 250.27 g/mol) for analytical method development and quality control.

The molecular framework of 4-Ethoxybenzene-1,2-diamine sulfate (C8H12N2OH2O4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 4-Ethoxybenzene-1,2-diamine sulfate 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.
