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-1,1’-spirobi[indene]-7,7’-diol.
CATO supplies (R)-2,2’,3,3’-Tetrahydro-1,1’-spirobi[indene]-7,7’-diol (CAS 223259-62-9), a certified reference material (molecular formula N/A, MW N/A g/mol) for analytical method development and quality control.
(R)-2,2’,3,3’-Tetrahydro-1,1’-spirobi[indene]-7,7’-diol is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).
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.
