Chemical Structure

tert-Butyl 3-hydroxy-4,5,6,8-tetrahydropyrazolo[3,4-c]azepine-7(1H)-carboxylate CAS 1445951-64-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-Butyl 3-hydroxy-4,5,6,8-tetrahydropyrazolo[3,4-c]azepine-7(1H)-carboxylate.

tert-Butyl 3-hydroxy-4,5,6,8-tetrahydropyrazolo[3,4-c]azepine-7(1H)-carboxylate (CAS 1445951-64-3) is a high-purity analytical reference standard with the molecular formula C12H19N3O3 and a molecular weight of 253.30 g/mol.

The molecular framework of tert-Butyl 3-hydroxy-4,5,6,8-tetrahydropyrazolo[3,4-c]azepine-7(1H)-carboxylate (C12H19N3O3) 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).

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