Description

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.

S-(2-((((5,5-dimethyl-4-oxohexyl)oxy)(4-nitrophenoxy)phosphoryl)oxy)ethyl) 2,2-dimethylpropanethioate (CAS 1770840-95-3) is a high-purity analytical reference standard with the molecular formula C21H32NO8PS and a molecular weight of 489.52 g/mol.

S-(2-((((5,5-dimethyl-4-oxohexyl)oxy)(4-nitrophenoxy)phosphoryl)oxy)ethyl) 2,2-dimethylpropanethioate (C21H32NO8PS) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), S-(2-((((5,5-dimethyl-4-oxohexyl)oxy)(4-nitrophenoxy)phosphoryl)oxy)ethyl) 2,2-dimethylpropanethioate 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.
