Description
CATO supplies 5-(((4-(Tert-butyl)phenyl)thio)methylene)-2,2-dimethyl-1,3-dioxane-4,6-dione (CAS 477866-41-4), a certified reference material (molecular formula C17H20O4S, MW 320.40 g/mol) for analytical method development and quality control.
Structurally, 5-(((4-(Tert-butyl)phenyl)thio)methylene)-2,2-dimethyl-1,3-dioxane-4,6-dione (C17H20O4S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 320.40 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 5-(((4-(Tert-butyl)phenyl)thio)methylene)-2,2-dimethyl-1,3-dioxane-4,6-dione 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.
