Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 172.16 g/mol gives O-Methylisourea Sulfate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
O-Methylisourea Sulfate (CAS 52328-05-9), molecular formula H2O4SC2H6N2O and molecular weight 172.16 g/mol, is a CATO reference standard with documented purity and traceability.
O-Methylisourea Sulfate (H2O4SC2H6N2O) contains an amide group, a sulfone group, a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 O-Methylisourea Sulfate 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.
