Teriflunomide Impurity 8 CAS 61865-29-0 chemical structure

Description

As a certified reference material (CRM), Teriflunomide Impurity 8 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.

Teriflunomide Impurity 8 (CAS 61865-29-0) is a high-purity analytical reference standard with the molecular formula C7H8FN and a molecular weight of 125.14 g/mol.

Structurally, Teriflunomide Impurity 8 (C7H8FN) contains a nitrile group, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 125.14 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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