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 Bicyclo[2.2.1]hept-2,5-diene.
Bicyclo[2.2.1]hept-2,5-diene (CAS 121-46-0), molecular formula C7H8 and molecular weight 92.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Bicyclo[2.2.1]hept-2,5-diene (C7H8) is characterized by an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, 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.
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.
