tert-Butyl ((5-formyl-1-methyl-1H-pyrazol-3-yl)methyl)carbamate (CAS 2137545-79-8), molecular formula C11H17N3O3 and molecular weight 239.27 g/mol, is a CATO reference standard with documented purity and traceability.
tert-Butyl ((5-formyl-1-methyl-1H-pyrazol-3-yl)methyl)carbamate (C11H17N3O3) contains an amino-acid-derived structure, an amide 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.
