14041-52-2 Ytterbium, isotope of mass 172 Ytterbium-172 172Yb CAS 14041-52-2 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 14041-52-2 Ytterbium, isotope of mass 172 Ytterbium-172 172Yb.

CATO supplies 14041-52-2 Ytterbium, isotope of mass 172 Ytterbium-172 172Yb (CAS 14041-52-2), a certified reference material (molecular formula [172Yb], MW 171.94 g/mol) for analytical method development and quality control.

The molecular framework of 14041-52-2 Ytterbium, isotope of mass 172 Ytterbium-172 172Yb ([172Yb]) is characterized by an inorganic composition. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
