Chemical Structure

Norborn-2-ene Impurity 2 CAS 7322-46-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Norborn-2-ene Impurity 2 (CAS 7322-46-5), molecular formula C12H12 and molecular weight 156.22 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Norborn-2-ene Impurity 2 (C12H12) contains an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 156.22 g/mol, it falls into the medium-molecular-weight range. 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).

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.
