Chemical Structure

4-(Benzyloxy)-8-isopropyl-2-(methylsulfonyl)pyrazolo[1,5-a][1,3,5]triazine CAS 1453476-79-3 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 4-(Benzyloxy)-8-isopropyl-2-(methylsulfonyl)pyrazolo[1,5-a][1,3,5]triazine.

4-(Benzyloxy)-8-isopropyl-2-(methylsulfonyl)pyrazolo[1,5-a][1,3,5]triazine (CAS 1453476-79-3) is a high-purity analytical reference standard with the molecular formula C16H18N4O3S and a molecular weight of 346.40 g/mol.

The molecular framework of 4-(Benzyloxy)-8-isopropyl-2-(methylsulfonyl)pyrazolo[1,5-a][1,3,5]triazine (C16H18N4O3S) is characterized by a nitrogen-containing heterocyclic scaffold, 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. 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), 4-(Benzyloxy)-8-isopropyl-2-(methylsulfonyl)pyrazolo[1,5-a][1,3,5]triazine 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.
