Chemical Structure

Praseodymium(III) oxide CAS 12036-32-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Praseodymium(III) oxide.

CATO supplies Praseodymium(III) oxide (CAS 12036-32-7), a certified reference material (molecular formula O3Pr2, MW 329.81 g/mol) for analytical method development and quality control.

Structurally, Praseodymium(III) oxide (O3Pr2) contains an inorganic composition. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 329.81 g/mol, it falls into the moderately-high-molecular-weight range.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
