Chemical Structure

Vitamin K1 Impurity 72 CAS 102608-53-7 chemical structure

Description

Owing to a hydroxyl group, an ether linkage, Vitamin K1 Impurity 72 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Vitamin K1 Impurity 72 (CAS 102608-53-7) is a certified pharmaceutical impurity reference standard with the molecular formula C20H40O and a molecular weight of 296.53 g/mol.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
