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 3-(Methyl-d3-thio)propionaldehyde (CAS 136430-27-8), a certified reference material (molecular formula C4H5D3OS, MW 107.19 g/mol) for analytical method development and quality control.
3-(Methyl-d3-thio)propionaldehyde (C4H5D3OS) contains deuterium isotope labeling, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
