Chemical Structure
Description
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.
CATO supplies 4-(propan-2-yloxy)thiophene-2-carboxylic acid (CAS 1469164-07-5), a certified reference material (molecular formula C8H14O3S, MW 190.26 g/mol) for analytical method development and quality control.
4-(propan-2-yloxy)thiophene-2-carboxylic acid (C8H14O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.
