Chemical Structure
Description
The molecular framework of tert-Butyl (5-formyl-1-methyl-1H-pyrazol-4-yl)carbamate (C10H15N3O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
tert-Butyl (5-formyl-1-methyl-1H-pyrazol-4-yl)carbamate (CAS 796845-65-3) is a high-purity analytical reference standard with the molecular formula C10H15N3O3 and a molecular weight of 225.24 g/mol.
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.
