Chemical Structure

1,1-Dimethylguanidine sulfate CAS 311-77-3 chemical structure

Description

1,1-Dimethylguanidine sulfate (H2O4SC3H9N3) 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.

1,1-Dimethylguanidine sulfate (CAS 311-77-3) is a high-purity analytical reference standard with the molecular formula H2O4SC3H9N3 and a molecular weight of 185.20 g/mol.

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.

As a certified reference material (CRM), 1,1-Dimethylguanidine sulfate 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.
