Chemical Structure
Description
CATO supplies D-Galactose-4-d (CAS 478518-71-7), a certified reference material (molecular formula C6H11DO6, MW 181.16 g/mol) for analytical method development and quality control.
Structurally, D-Galactose-4-d (C6H11DO6) contains deuterium isotope labeling, a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 181.16 g/mol, it falls into the medium-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.
