Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including L-Isoleucine 7-amido-4-methylcoumarin trifluroacetate.
L-Isoleucine 7-amido-4-methylcoumarin trifluroacetate (CAS 191723-53-2), molecular formula C16H20N2O3C2HF3O2 and molecular weight 402.37 g/mol, is a CATO reference standard with documented purity and traceability.
L-Isoleucine 7-amido-4-methylcoumarin trifluroacetate (C16H20N2O3C2HF3O2) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), L-Isoleucine 7-amido-4-methylcoumarin trifluroacetate 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.
