Chemical Structure
Description
The occurrence of 23303-71-1 lithiumbromide (libr), monohydrate (9ci) is closely related to a salt form, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 23303-71-1 lithiumbromide (libr), monohydrate (9ci) (CAS 23303-71-1), a certified reference material (molecular formula BrLiH2O, MW 104.86 g/mol) for analytical method development and quality control.
The molecular framework of 23303-71-1 lithiumbromide (libr), monohydrate (9ci) (BrLiH2O) is characterized by a salt form, bromine substitution. 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. 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.
