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 5-(tert-Butyl)-3-(4-chlorophenyl)-N-(2-methoxyethyl)pyrazolo[1,5-a]pyrimidin-7-amine.
5-(tert-Butyl)-3-(4-chlorophenyl)-N-(2-methoxyethyl)pyrazolo[1,5-a]pyrimidin-7-amine (CAS 896806-64-7) is a high-purity analytical reference standard with the molecular formula C19H23ClN4O and a molecular weight of 358.87 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 5-(tert-Butyl)-3-(4-chlorophenyl)-N-(2-methoxyethyl)pyrazolo[1,5-a]pyrimidin-7-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-(tert-Butyl)-3-(4-chlorophenyl)-N-(2-methoxyethyl)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.
