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 2,6,7-trihydroxy-9-(2-hydroxyphenyl)-3h-xanthen-3-one 36854-57-6 AR-1D4631 (CAS 36854-57-6), a certified reference material (molecular formula C10H17ClO, MW 188.69 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H17ClO, 2,6,7-trihydroxy-9-(2-hydroxyphenyl)-3h-xanthen-3-one 36854-57-6 AR-1D4631 contains a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 188.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
