Chemical Structure

Vitamin K1 Impurity 75 CAS 36232-38-9 chemical structure

Description

Owing to an organic framework, Vitamin K1 Impurity 75 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.53 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 75 (CAS 36232-38-9) is a certified pharmaceutical impurity reference standard with the molecular formula C20H40 and a molecular weight of 280.53 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.

As a certified reference material (CRM), Vitamin K1 Impurity 75 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.
