Description
CATO supplies 2-Ethylhexyl diphenyl phosphite (CAS 15647-08-2), a certified reference material (molecular formula C20H27O3P, MW 346.40 g/mol) for analytical method development and quality control.
Structurally, 2-Ethylhexyl diphenyl phosphite (C20H27O3P) contains a steroid core, a phosphonate group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 346.40 g/mol, it falls into the moderately-high-molecular-weight range. 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), 2-Ethylhexyl diphenyl phosphite 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.
