Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2,2',2'-Tetramethyl-2H,2'H-[5,5'-bibenzo[h]chromene]-6,6'-diol.
CATO supplies 2,2,2',2'-Tetramethyl-2H,2'H-[5,5'-bibenzo[h]chromene]-6,6'-diol (CAS 24449-39-6), a certified reference material (molecular formula C30H26O4, MW 450.53 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, 2,2,2',2'-Tetramethyl-2H,2'H-[5,5'-bibenzo[h]chromene]-6,6'-diol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 450.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), 2,2,2',2'-Tetramethyl-2H,2'H-[5,5'-bibenzo[h]chromene]-6,6'-diol 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.
