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.
2,2-Bis(hydroxymethyl)propane-1,3-diyl didocosanoate (CAS 68258-72-0), molecular formula C49H96O6 and molecular weight 781.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,2-Bis(hydroxymethyl)propane-1,3-diyl didocosanoate (C49H96O6) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
