Description
As a certified reference material (CRM), Methyl-5-Norbornene-2,3-Dicarboxylic Anhydride 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.
Methyl-5-Norbornene-2,3-Dicarboxylic Anhydride (CAS 14806-35-0), molecular formula C10H10O3 and molecular weight 178.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl-5-Norbornene-2,3-Dicarboxylic Anhydride (C10H10O3) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
