3-bromo-2-ethyl-5-(propan-2-yl)pyrazolo[1,5-a]pyrimidin-7-amine CAS 2905749-85-9

Description

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.

3-bromo-2-ethyl-5-(propan-2-yl)pyrazolo[1,5-a]pyrimidin-7-amine (CAS 2905749-85-9), molecular formula C11H15BrN4 and molecular weight 283.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 3-bromo-2-ethyl-5-(propan-2-yl)pyrazolo[1,5-a]pyrimidin-7-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures 3-bromo-2-ethyl-5-(propan-2-yl)pyrazolo[1,5-a]pyrimidin-7-amine 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.
