Menaquinone impurity 29 CAS CATO-C4X-207629

Description

Compared with other compounds in its class, the molecular weight of 444.65 g/mol gives Menaquinone impurity 29 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Menaquinone impurity 29 (CAS CATO-C4X-207629), a pharmacopoeial impurity reference standard (molecular formula C31H40O2, MW 444.65 g/mol) used for the identification and quantification of trace impurities in APIs.

Menaquinone impurity 29 (C31H40O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), Menaquinone impurity 29 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.
