Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 235.25 g/mol gives 3-(Ethylamino)phenol hemisulfate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(Ethylamino)phenol hemisulfate (CAS 1274892-48-6) is a high-purity analytical reference standard with the molecular formula C8H11NOH2O4S and a molecular weight of 235.25 g/mol.
3-(Ethylamino)phenol hemisulfate (C8H11NOH2O4S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 3-(Ethylamino)phenol hemisulfate 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.
