Chemical Structure

5-Butyl-7-ethoxypyrazolo[1,5-a]pyrimidine CAS 189018-32-4 chemical structure

Description

5-Butyl-7-ethoxypyrazolo[1,5-a]pyrimidine (CAS 189018-32-4) is a high-purity analytical reference standard with the molecular formula C12H17N3O and a molecular weight of 219.28 g/mol.

The molecular framework of 5-Butyl-7-ethoxypyrazolo[1,5-a]pyrimidine (C12H17N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 5-Butyl-7-ethoxypyrazolo[1,5-a]pyrimidine 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.
