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 Tetrahydro-2H-3,5-methanocyclopenta[b]furan-2,6(3H)-dione.
Tetrahydro-2H-3,5-methanocyclopenta[b]furan-2,6(3H)-dione (CAS 16479-73-5) is a high-purity analytical reference standard with the molecular formula C8H8O3 and a molecular weight of 152.15 g/mol.
The molecular framework of Tetrahydro-2H-3,5-methanocyclopenta[b]furan-2,6(3H)-dione (C8H8O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Tetrahydro-2H-3,5-methanocyclopenta[b]furan-2,6(3H)-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.
