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 7-Hydroxy-5-pentyl-[1,2,4]triazolo[1,5-a]pyrimidine-2-carboxylic acid.
7-Hydroxy-5-pentyl-[1,2,4]triazolo[1,5-a]pyrimidine-2-carboxylic acid (CAS 54289-36-0), molecular formula C11H14N4O3 and molecular weight 250.25 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 7-Hydroxy-5-pentyl-[1,2,4]triazolo[1,5-a]pyrimidine-2-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 7-Hydroxy-5-pentyl-[1,2,4]triazolo[1,5-a]pyrimidine-2-carboxylic acid 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.
