Chemical Structure

tert-butyl (6S)-3-(4-fluorophenyl)-6-methyl-4H,5H,6H,7H-pyrazolo[1,5-a]pyrazine-5-carboxylate CAS 1967003-64-0 chemical structure

Description

The occurrence of tert-butyl (6S)-3-(4-fluorophenyl)-6-methyl-4H,5H,6H,7H-pyrazolo[1,5-a]pyrazine-5-carboxylate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies tert-butyl (6S)-3-(4-fluorophenyl)-6-methyl-4H,5H,6H,7H-pyrazolo[1,5-a]pyrazine-5-carboxylate (CAS 1967003-64-0), a certified reference material (molecular formula C18H22FN3O2, MW 331.38 g/mol) for analytical method development and quality control.

The molecular framework of tert-butyl (6S)-3-(4-fluorophenyl)-6-methyl-4H,5H,6H,7H-pyrazolo[1,5-a]pyrazine-5-carboxylate (C18H22FN3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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 (6S)-3-(4-fluorophenyl)-6-methyl-4H,5H,6H,7H-pyrazolo[1,5-a]pyrazine-5-carboxylate 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.
