Chemical Structure
Description
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.
Pyridinium, 2-(methoxycarbonyl)-1-methyl- (CAS 45867-57-0), molecular formula C8H10NO2 and molecular weight 152.17 g/mol, is a CATO reference standard with documented purity and traceability.
Pyridinium, 2-(methoxycarbonyl)-1-methyl- (C8H10NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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).
CATO manufactures Pyridinium, 2-(methoxycarbonyl)-1-methyl- 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.
