Description
CATO supplies 1338495-24-1 4-(1,3-Benzodioxol-5-ylmethyl)tetrahydro-2H-pyran-4-carboxylic acid (CAS 1338495-24-1), a certified reference material (molecular formula C14H16O5, MW 264.27 g/mol) for analytical method development and quality control.
1338495-24-1 4-(1,3-Benzodioxol-5-ylmethyl)tetrahydro-2H-pyran-4-carboxylic acid (C14H16O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
