Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(4-Methoxyphenyl)-6-(phenylsulfonyl)pyrazolo[1,5-a]pyrimidin-7-amine (CAS 866050-00-2) is a high-purity analytical reference standard with the molecular formula C19H16N4O3S and a molecular weight of 380.42 g/mol.
The molecular framework of 3-(4-Methoxyphenyl)-6-(phenylsulfonyl)pyrazolo[1,5-a]pyrimidin-7-amine (C19H16N4O3S) is characterized by a steroid core, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 3-(4-Methoxyphenyl)-6-(phenylsulfonyl)pyrazolo[1,5-a]pyrimidin-7-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
