Chemical Structure
Description
CATO supplies cis-4-Hydroxytetrahydrofuran-2-carboxylic acid (CAS 2209-08-7), a certified reference material (molecular formula C5H8O4, MW 132.11 g/mol) for analytical method development and quality control.
cis-4-Hydroxytetrahydrofuran-2-carboxylic acid (C5H8O4) contains a carbohydrate-derived structure. 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.
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.
