Chemical Structure

Levosimendan Impurity 44 CAS 63514-63-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 270.12 g/mol gives Levosimendan Impurity 44 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Levosimendan Impurity 44 (CAS 63514-63-6), a pharmacopoeial impurity reference standard (molecular formula C11H12BrNO2, MW 270.12 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, bromine substitution, Levosimendan Impurity 44 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 270.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 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.

CATO manufactures Levosimendan Impurity 44 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
