Chemical Structure

Butylphthalide Impurity 6 CAS 162050-42-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 206.24 g/mol gives Butylphthalide Impurity 6 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Butylphthalide Impurity 6 (CAS 162050-42-2), a pharmacopoeial impurity reference standard (molecular formula C12H14O3, MW 206.24 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C12H14O3, Butylphthalide Impurity 6 contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 206.24 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.

As a certified reference material (CRM), Butylphthalide Impurity 6 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.
