7-(Ethylamino)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-6-ol CAS 58256-06-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-(Ethylamino)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-6-ol.

7-(Ethylamino)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-6-ol (CAS 58256-06-7) is a high-purity analytical reference standard with the molecular formula C8H11N5O and a molecular weight of 193.21 g/mol.

The molecular framework of 7-(Ethylamino)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-6-ol (C8H11N5O) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
