Lovastatin Impurity 37 CAS CATO-C4X-168437 chemical structure

Description

Lovastatin Impurity 37 (CAS CATO-C4X-168437) is a certified pharmaceutical impurity reference standard with the molecular formula C11H22C10H18C2H6 and a molecular weight of 322.62 g/mol.

Structurally, Lovastatin Impurity 37 (C11H22C10H18C2H6) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 322.62 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
