Chemical Structure

Tert-butyl 3-cyano-1,4,6,7-tetrahydro-5H-pyrazolo[4,3-c]pyridine-5-carboxylate CAS 1781647-67-3 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-cyano-1,4,6,7-tetrahydro-5H-pyrazolo[4,3-c]pyridine-5-carboxylate.

Tert-butyl 3-cyano-1,4,6,7-tetrahydro-5H-pyrazolo[4,3-c]pyridine-5-carboxylate (CAS 1781647-67-3) is a high-purity analytical reference standard with the molecular formula C12H16N4O2 and a molecular weight of 248.28 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Tert-butyl 3-cyano-1,4,6,7-tetrahydro-5H-pyrazolo[4,3-c]pyridine-5-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 3-cyano-1,4,6,7-tetrahydro-5H-pyrazolo[4,3-c]pyridine-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.
