Repaglinide Impurity 14 CAS 107362-46-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Repaglinide Impurity 14.

Repaglinide Impurity 14 (CAS 107362-46-9) is a certified pharmaceutical impurity reference standard with the molecular formula C19H24N2 and a molecular weight of 280.41 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Repaglinide Impurity 14 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
