Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 692.20 g/mol gives Blue Tetrazolium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Blue Tetrazolium (CAS 1871-22-3), a certified reference material (molecular formula C40H32N8O2Cl, MW 692.20 g/mol) for analytical method development and quality control.
Blue Tetrazolium (C40H32N8O2Cl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures Blue Tetrazolium 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.
