Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 91.18 g/mol gives 3-aminopropane-1-thiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-aminopropane-1-thiol (CAS 462-47-5), a certified reference material (molecular formula C3H9NS, MW 91.18 g/mol) for analytical method development and quality control.
The molecular framework of 3-aminopropane-1-thiol (C3H9NS) is characterized by sulfur-containing functionality. 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), 3-aminopropane-1-thiol 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.
