Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 157.66 g/mol gives 2-(ethanesulfinyl)ethan-1-amine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(ethanesulfinyl)ethan-1-amine hydrochloride (CAS 176240-96-3), molecular formula C4H11NOSHCl and molecular weight 157.66 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(ethanesulfinyl)ethan-1-amine hydrochloride (C4H11NOSHCl) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 2-(ethanesulfinyl)ethan-1-amine hydrochloride 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.
