Butylphthalide Impurity 7 CAS 122654-56-2

Description

As a certified reference material (CRM), Butylphthalide Impurity 7 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 Butylphthalide Impurity 7 (CAS 122654-56-2), a pharmacopoeial impurity reference standard (molecular formula C12H15NO, MW 189.25 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C12H15NO, Butylphthalide Impurity 7 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 189.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
