Chemical Structure
Description
The occurrence of Pentaerythrityl tetrastearate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Pentaerythrityl tetrastearate (CAS 115-83-3), molecular formula C77H148O8C69H132O8 and molecular weight 2291.83 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Pentaerythrityl tetrastearate is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 2291.83 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Pentaerythrityl tetrastearate 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.
