Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 995.59 g/mol gives DM4-SPDB distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
DM4-SPDB (CAS 1626359-62-3) is a high-purity analytical reference standard with the molecular formula C46H63ClN4O14S2 and a molecular weight of 995.59 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, DM4-SPDB is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 995.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 DM4-SPDB 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.
