Description
CATO supplies tert-Butyl N-{4H,5H,6H,7H-pyrazolo[1,5-a]pyrimidin-3-yl}carbamate (CAS 2091447-06-0), a certified reference material (molecular formula C11H18N4O2, MW 238.29 g/mol) for analytical method development and quality control.
The molecular framework of tert-Butyl N-{4H,5H,6H,7H-pyrazolo[1,5-a]pyrimidin-3-yl}carbamate (C11H18N4O2) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 tert-Butyl N-{4H,5H,6H,7H-pyrazolo[1,5-a]pyrimidin-3-yl}carbamate 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.
