Chemical Structure
Description
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.
CATO supplies Sodium chromate tetrahydrate (CAS 10034-82-9), a certified reference material (molecular formula CrO4NaH2O, MW 157.00 g/mol) for analytical method development and quality control.
Sodium chromate tetrahydrate (CrO4NaH2O) contains an inorganic composition. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
