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.
Chromium(Ⅲ)Hydroxiden (CAS 1308-14-1) is a high-purity analytical reference standard with the molecular formula H3CrO3 and a molecular weight of 103.02 g/mol.
Based on its molecular formula H3CrO3, Chromium(Ⅲ)Hydroxiden contains an inorganic composition; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 103.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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.
