Description
CATO supplies 5-methylthiophene-3-carbaldehyde (CAS 29421-72-5), a certified reference material (molecular formula C6H10OS, MW 130.21 g/mol) for analytical method development and quality control.
5-methylthiophene-3-carbaldehyde (C6H10OS) contains 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.
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.
