Chemical Structure

Minodronic Impurity 33 CAS 114736-26-4 chemical structure

Description

As a process- or degradation-related impurity, Minodronic Impurity 33 (CAS 114736-26-4, C8H14O4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Minodronic Impurity 33 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
