Chemical Structure

Formoterol Impurity 49 CAS 14367-46-5 chemical structure

Description

As a certified reference material (CRM), Formoterol Impurity 49 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.

CATO supplies Formoterol Impurity 49 (CAS 14367-46-5), a pharmacopoeial impurity reference standard (molecular formula C12H19NO, MW 193.29 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Formoterol Impurity 49 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 193.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
