Chemical Structure

tert-butyl 4-nitro-1H-pyrazole-1-carboxylate CAS 1018446-96-2 chemical structure

Description

The occurrence of tert-butyl 4-nitro-1H-pyrazole-1-carboxylate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

tert-butyl 4-nitro-1H-pyrazole-1-carboxylate (CAS 1018446-96-2) is a high-purity analytical reference standard with the molecular formula C8H15N3O4 and a molecular weight of 217.22 g/mol.

The molecular framework of tert-butyl 4-nitro-1H-pyrazole-1-carboxylate (C8H15N3O4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
