Chemical Structure
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.
Butylene Terephthalate Cyclic Pentamer (CAS 82298-33-7), molecular formula C60H60O20 and molecular weight 1101.11 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Butylene Terephthalate Cyclic Pentamer (C60H60O20) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 31.0, corresponding to approximately 31 ring(s) or double-bond equivalent(s). With a molecular weight of 1101.11 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
