Chemical Structure
Description
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.
2,3,4,9-Tetrahydro-1H-carbazol-1-one O-(tert-butylcarbamoyl) oxime (CAS 860612-31-3) is a high-purity analytical reference standard with the molecular formula C17H21N3O2 and a molecular weight of 299.37 g/mol.
2,3,4,9-Tetrahydro-1H-carbazol-1-one O-(tert-butylcarbamoyl) oxime (C17H21N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
