[1,2,4]triazolo[1,5-a]pyrimidin-7-ol CAS 4866-61-9

Description

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

[1,2,4]triazolo[1,5-a]pyrimidin-7-ol (CAS 4866-61-9), molecular formula C5H12N4O and molecular weight 144.17 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, [1,2,4]triazolo[1,5-a]pyrimidin-7-ol (C5H12N4O) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 144.17 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
