Owing to chlorine substitution, Vitamin K1 Impurity 65 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.98 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies Vitamin K1 Impurity 65 (CAS CATO-C4X-220765), a pharmacopoeial impurity reference standard (molecular formula C20H39Cl, MW 314.98 g/mol) used for the identification and quantification of trace impurities in APIs.
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), Vitamin K1 Impurity 65 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.
