Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (R)-2,2',3,3'-Tetrahydro-6,6'-diiodo-1,1'-spirobi[1H-indene]-7,7'-diol.
CATO supplies (R)-2,2',3,3'-Tetrahydro-6,6'-diiodo-1,1'-spirobi[1H-indene]-7,7'-diol (CAS 1435948-36-9), a certified reference material (molecular formula C17H14I2O2, MW 504.10 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, iodine substitution, (R)-2,2',3,3'-Tetrahydro-6,6'-diiodo-1,1'-spirobi[1H-indene]-7,7'-diol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 504.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
