Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including n-(4-Fluorobenzyl)-2-(3-oxo-6,7,8,9-tetrahydro-3h-[1,2,4]triazolo[4,3-a]azepin-2(5h)-yl)acetamide.
n-(4-Fluorobenzyl)-2-(3-oxo-6,7,8,9-tetrahydro-3h-[1,2,4]triazolo[4,3-a]azepin-2(5h)-yl)acetamide (CAS 930547-78-7), molecular formula C16H19FN4O2 and molecular weight 318.35 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, n-(4-Fluorobenzyl)-2-(3-oxo-6,7,8,9-tetrahydro-3h-[1,2,4]triazolo[4,3-a]azepin-2(5h)-yl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.35 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).
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), n-(4-Fluorobenzyl)-2-(3-oxo-6,7,8,9-tetrahydro-3h-[1,2,4]triazolo[4,3-a]azepin-2(5h)-yl)acetamide 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.
