Description

63126-89-6 Clinitest 1,2,3-Propanetricarboxylic acid, 2-hydroxy-, mixt. with copper(2+) sulfate (1:1), sodium hydrogen carbonate and sodium hydroxide (Na(OH)) 1,2,3-Propanetricarboxylic acid, 2-hydroxy-, mixt. with copper(2+) sulfate (1:1), sodium hydrogen carbonate and sodium hydroxide (C6H8O7O4SCuCHO3NaHO) contains a carbohydrate-derived structure, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

63126-89-6 Clinitest 1,2,3-Propanetricarboxylic acid, 2-hydroxy-, mixt. with copper(2+) sulfate (1:1), sodium hydrogen carbonate and sodium hydroxide (Na(OH)) 1,2,3-Propanetricarboxylic acid, 2-hydroxy-, mixt. with copper(2+) sulfate (1:1), sodium hydrogen carbonate and sodium hydroxide (CAS 63126-89-6) is a high-purity analytical reference standard with the molecular formula C6H8O7O4SCuCHO3NaHO and a molecular weight of 452.74 g/mol.

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.
