Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 171.17 g/mol gives 1-Methylguanidine hemisulfate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Methylguanidine hemisulfate (CAS 598-12-9) is a high-purity analytical reference standard with the molecular formula H2O4SC2H7N3 and a molecular weight of 171.17 g/mol.
1-Methylguanidine hemisulfate (H2O4SC2H7N3) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-Methylguanidine hemisulfate 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.
