Chemical Structure
Description
The occurrence of Terbinafine Impurity 4 (Mixture of Z and E Isomers) is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Terbinafine Impurity 4 (Mixture of Z and E Isomers) (CAS 114311-70-5), molecular formula C9H14O and molecular weight 138.21 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Terbinafine Impurity 4 (Mixture of Z and E Isomers) (C9H14O) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 138.21 g/mol, it falls into the low-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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
