Chemical Structure

Letrozole Impurity 5 CAS 124213-98-5 chemical structure

Description

The occurrence of Letrozole Impurity 5 is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Letrozole Impurity 5 (CAS 124213-98-5) is a high-purity analytical reference standard with the molecular formula C2H6N4 and a molecular weight of 86.10 g/mol.

Based on its molecular formula C2H6N4, Letrozole Impurity 5 contains a nitrile group; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 86.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Letrozole Impurity 5 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.
