Chemical Structure
Description
The occurrence of (Methylamino)thiourea is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (Methylamino)thiourea (CAS 21185-13-7), a certified reference material (molecular formula C2H7N3S, MW 105.16 g/mol) for analytical method development and quality control.
Based on its molecular formula C2H7N3S, (Methylamino)thiourea contains sulfur-containing functionality; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 105.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), (Methylamino)thiourea 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.
