Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Methoxy-5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazine; trifluoroacetic acid.
3-Methoxy-5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazine; trifluoroacetic acid (CAS 723286-83-7), molecular formula C6H10N4OC2HF3O2 and molecular weight 268.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Methoxy-5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazine; trifluoroacetic acid (C6H10N4OC2HF3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 268.19 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
