Chemical Structure

2-{5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazin-3-yl}pyridine CAS 1159522-34-5 chemical structure

Description

As a certified reference material (CRM), 2-{5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazin-3-yl}pyridine 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.

2-{5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazin-3-yl}pyridine (CAS 1159522-34-5), molecular formula C10H11N5 and molecular weight 201.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2-{5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazin-3-yl}pyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
