Description
CATO supplies [(1R,4S)-7,7-dimethyl-2-oxo-norbornan-1-yl]methanesulfonic acid;hemi((2R)-piperazine-2-carboxylic acid) (CAS 278790-39-9), a certified reference material (molecular formula C10H16O4SC5H10N2O2, MW 362.44 g/mol) for analytical method development and quality control.
[(1R,4S)-7,7-dimethyl-2-oxo-norbornan-1-yl]methanesulfonic acid;hemi((2R)-piperazine-2-carboxylic acid) (C10H16O4SC5H10N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. 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.
CATO manufactures [(1R,4S)-7,7-dimethyl-2-oxo-norbornan-1-yl]methanesulfonic acid;hemi((2R)-piperazine-2-carboxylic acid) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
