Chemical Structure
Description
The occurrence of Thiourea Dioxide is closely related to a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Thiourea Dioxide (CAS 1758-73-2), a certified reference material (molecular formula CH4N2O2S, MW 108.12 g/mol) for analytical method development and quality control.
Structurally, Thiourea Dioxide (CH4N2O2S) contains a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 108.12 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.
CATO manufactures Thiourea Dioxide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
