Chemical Structure

Baricitinib Impurity N3 CAS 136823-41-1 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Baricitinib Impurity N3 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 154.21 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).

Baricitinib Impurity N3 (CAS 136823-41-1) is a certified pharmaceutical impurity reference standard with the molecular formula C9H14O2 and a molecular weight of 154.21 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.
