Description

Compared with other compounds in its class, the molecular weight of 660.75 g/mol gives m-PEG12-COO-propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

m-PEG12-COO-propanoic acid (CAS 2168540-50-7), molecular formula C29H56O16 and molecular weight 660.75 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, m-PEG12-COO-propanoic acid (C29H56O16) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 660.75 g/mol, it falls into the high-molecular-weight range.

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.

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.
