Chemical Structure
Description
The occurrence of 1-Methylpyrrolidine-3-thiol is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-Methylpyrrolidine-3-thiol (CAS 91832-88-1), a certified reference material (molecular formula C5H11NS, MW 117.21 g/mol) for analytical method development and quality control.
The molecular framework of 1-Methylpyrrolidine-3-thiol (C5H11NS) 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.
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), 1-Methylpyrrolidine-3-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.
