CATO supplies 70849-21-7 D-Xylose-1-13C (3R,4S,5R)-(213C)oxane-2,3,4,5-tetrol (CAS 70849-21-7), a certified reference material (molecular formula C4[13C]H10O5, MW 151.12 g/mol) for analytical method development and quality control.
Based on its molecular formula C4[13C]H10O5, 70849-21-7 D-Xylose-1-13C (3R,4S,5R)-(213C)oxane-2,3,4,5-tetrol contains a carbohydrate-derived structure; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 151.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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.
