Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 240.30 g/mol gives DABCO-Bis(sulfur dioxide) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies DABCO-Bis(sulfur dioxide) (CAS 119752-83-9), a certified reference material (molecular formula C6H12N2O4S2, MW 240.30 g/mol) for analytical method development and quality control.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, DABCO-Bis(sulfur dioxide) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), DABCO-Bis(sulfur dioxide) 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.
