Chemical Structure
Description
CATO supplies 2-(1-(Methylsulfonyl)cyclopropyl)acetic acid (CAS 1887209-88-2), a certified reference material (molecular formula C6H10O4S, MW 178.21 g/mol) for analytical method development and quality control.
2-(1-(Methylsulfonyl)cyclopropyl)acetic acid (C6H10O4S) 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.
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.
