Chemical Structure

Praseodymium(III) chloride hydrate CAS 19423-77-9 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) chloride hydrate.

CATO supplies Praseodymium(III) chloride hydrate (CAS 19423-77-9), a certified reference material (molecular formula Cl3PrH2O, MW 265.27 g/mol) for analytical method development and quality control.

Structurally, Praseodymium(III) chloride hydrate (Cl3PrH2O) contains chlorine substitution. 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 265.27 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
