Structurally, 7775-11-3 6A49BO6K4M Sodium chromate Sodium chromate(VI) Chromic acid, disodium salt Chromic acid (H2CrO4), sodium salt (1:2) Chromic acid (H2CrO4), disodium salt Caswell No. 757 CCRIS 883 Chromate of soda Chromium disodium oxide Chromium sodium oxide (CrNa2O4) Disodium chromate EINECS 231-889-5 EPA Pesticide Chemical Code 068303 HSDB 2962 Neutral sodium chromate Rachromate Chromitope sodium UNII-6A49BO6K4M EC 231-889-5 Sodium chromate [Chromium and chromium compounds] (CrO4Na) contains an inorganic composition. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 138.98 g/mol, it falls into the low-molecular-weight range.
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.
