Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(Diaminomethylene)urea sulfate (CAS 5338-16-9), molecular formula C2H6N4OH2O4S and molecular weight 200.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(Diaminomethylene)urea sulfate (C2H6N4OH2O4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, an ether linkage. 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.
CATO manufactures 1-(Diaminomethylene)urea 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.
