Chemical Structure
Description
CATO supplies O-ethylisoureahydrogensulfate (CAS 68303-38-8), a certified reference material (molecular formula H2O4SC3H8N2O, MW 186.18 g/mol) for analytical method development and quality control.
O-ethylisoureahydrogensulfate (H2O4SC3H8N2O) 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 O-ethylisoureahydrogensulfate 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.
