Based on its molecular formula C33H52O8, 4196-86-5 U7L44GIS4O Pentaerythrityl tetrabenzoate 2,2-Bis((benzoyloxy)methyl)-1,3-propanediol dibenzoate Pentaerythritol tetrabenzoate 1,3-Propanediol, 2,2-bis((benzoyloxy)methyl)-, 1,3-dibenzoate 1,3-Propanediol, 2,2-bis((benzoyloxy)methyl)-, dibenzoate 3-09-00-00688 (Beilstein Handbook Reference) Benzoflex S-552 Benzoic acid, tetraester with pentaerythritol 2,2-Bis((benzoyloxy)methyl)dibenzoate propanediol BRN 3513249 CCRIS 5971 EINECS 224-079-8 NSC 166502 UNII-U7L44GIS4O contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 576.76 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
