Chemical Structure

Acetic acid, terbium salt(1:x) CAS 16922-07-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 235.99 g/mol gives Acetic acid, terbium salt(1:x) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Acetic acid, terbium salt(1:x) (CAS 16922-07-9), a certified reference material (molecular formula TbC2H3O2H2O, MW 235.99 g/mol) for analytical method development and quality control.

The molecular framework of Acetic acid, terbium salt(1:x) (TbC2H3O2H2O) is characterized by a carboxylic acid group, an ether linkage. 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.
