Chemical Structure

Formoterol Hemifumarate CAS CATO-C4X-152543 chemical structure

Description

The occurrence of Formoterol Hemifumarate is closely related to a structurally diverse molecular composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Formoterol Hemifumarate (CAS CATO-C4X-152543), molecular formula N/A and molecular weight N/A g/mol, is a CATO reference standard with documented purity and traceability.

Formoterol Hemifumarate is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Formoterol Hemifumarate 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.
