Chemical Structure

Mal-PEG2-C2-Boc CAS 1374666-31-5 chemical structure

Description

Mal-PEG2-C2-Boc (CAS 1374666-31-5), molecular formula C15H23NO6 and molecular weight 313.35 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C15H23NO6, Mal-PEG2-C2-Boc contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 313.35 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.

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.
