Chemical Structure
Description
Decyclopentyl Zafirlukast-d3 Methyl Ester (C27H24D3N3O6S) contains deuterium isotope labeling, a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
Decyclopentyl Zafirlukast-d3 Methyl Ester (CAS 1795011-90-3) is a high-purity analytical reference standard with the molecular formula C27H24D3N3O6S and a molecular weight of 524.60 g/mol.
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), Decyclopentyl Zafirlukast-d3 Methyl Ester 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.
