Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 516.80 g/mol gives Vitamin K1 Impurity 47 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Vitamin K1 Impurity 47 (CAS 2682052-39-5), a pharmacopoeial impurity reference standard (molecular formula C36H52O2, MW 516.80 g/mol) used for the identification and quantification of trace impurities in APIs.
Vitamin K1 Impurity 47 (C36H52O2) 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.
CATO manufactures Vitamin K1 Impurity 47 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.
