Chemical Structure

Lovastatin Impurity 45 CAS CATO-C4X-168445 chemical structure

Description

Owing to an organic framework, Lovastatin Impurity 45 is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 275.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies Lovastatin Impurity 45 (CAS CATO-C4X-168445), a pharmacopoeial impurity reference standard (molecular formula C9H20C6H14CH5NC2H6, MW 275.56 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.

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.
