Chemical Structure
Description
2-Aminoethyl hydrogen sulfate (CAS 926-39-6), molecular formula C2H7NO4S and molecular weight 141.15 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Aminoethyl hydrogen sulfate (C2H7NO4S) contains an amide group, a sulfone group, a carboxylic acid group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 141.15 g/mol, it falls into the low-molecular-weight range. 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), 2-Aminoethyl hydrogen 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.
