Chemical Structure
Description
The occurrence of Copper(II) tartrate hydrate 946843-80-7 Cupric tartrate hydrate Tartaric acid cupric salt is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Copper(II) tartrate hydrate 946843-80-7 Cupric tartrate hydrate Tartaric acid cupric salt (CAS 946843-80-7), a certified reference material (molecular formula C4H4O6CuH2O, MW 229.63 g/mol) for analytical method development and quality control.
Copper(II) tartrate hydrate 946843-80-7 Cupric tartrate hydrate Tartaric acid cupric salt (C4H4O6CuH2O) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
