6-Benzyl-3-(3,4-dimethoxyphenyl)-2,5-dimethylpyrazolo[1,5-a]pyrimidin-7(1H)-one CAS 838890-78-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Benzyl-3-(3,4-dimethoxyphenyl)-2,5-dimethylpyrazolo[1,5-a]pyrimidin-7(1H)-one.

6-Benzyl-3-(3,4-dimethoxyphenyl)-2,5-dimethylpyrazolo[1,5-a]pyrimidin-7(1H)-one (CAS 838890-78-1) is a high-purity analytical reference standard with the molecular formula C23H23N3O3 and a molecular weight of 389.45 g/mol.

The molecular framework of 6-Benzyl-3-(3,4-dimethoxyphenyl)-2,5-dimethylpyrazolo[1,5-a]pyrimidin-7(1H)-one (C23H23N3O3) is characterized by a steroid core, an amide 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. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 6-Benzyl-3-(3,4-dimethoxyphenyl)-2,5-dimethylpyrazolo[1,5-a]pyrimidin-7(1H)-one 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.
