Description
As a certified reference material (CRM), 7H-Indeno[5,6-b]Furan 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 7H-Indeno[5,6-b]Furan (CAS 3573-32-8), a certified reference material (molecular formula C11H8O, MW 156.18 g/mol) for analytical method development and quality control.
Structurally, 7H-Indeno[5,6-b]Furan (C11H8O) contains a hydroxyl group, an ether linkage, an aromatic ring system. 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 156.18 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
