Chemical Structure
Description
As a certified reference material (CRM), (((5-Chlorobenzo[d]thiazol-2-yl)sulfinyl)methyl)diphenylphosphine oxide 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 (((5-Chlorobenzo[d]thiazol-2-yl)sulfinyl)methyl)diphenylphosphine oxide (CAS 1956340-17-2), a certified reference material (molecular formula C20H15ClNO2PS2, MW 431.90 g/mol) for analytical method development and quality control.
(((5-Chlorobenzo[d]thiazol-2-yl)sulfinyl)methyl)diphenylphosphine oxide (C20H15ClNO2PS2) contains a steroid core, an amide group, a sulfone group, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
