Chemical Structure
Description
As a certified reference material (CRM), Methanaminium methoxydimethyl methyl sulfate (1:1) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies Methanaminium methoxydimethyl methyl sulfate (1:1) (CAS 21511-55-7), a certified reference material (molecular formula CH3O4SC4H10NO, MW 199.22 g/mol) for analytical method development and quality control.
Methanaminium methoxydimethyl methyl sulfate (1:1) (CH3O4SC4H10NO) contains a carbohydrate-derived structure, an amide group, a sulfone group. 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.
