Chemical Structure
Description
The occurrence of Monooctyl Phthalate-d4 is closely related to deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Monooctyl Phthalate-d4 (CAS 1398065-74-1), molecular formula C16H18D4O4 and molecular weight 282.37 g/mol, is a CATO reference standard with documented purity and traceability.
Monooctyl Phthalate-d4 (C16H18D4O4) contains deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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).
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), Monooctyl Phthalate-d4 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.
