Chemical Structure

Boc-NH-PEG12-CH2CH2COOH CAS 1415981-79-1 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.

Boc-NH-PEG12-CH2CH2COOH (CAS 1415981-79-1), molecular formula C32H63NO16 and molecular weight 717.84 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Boc-NH-PEG12-CH2CH2COOH (C32H63NO16) contains an amide group, 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 717.84 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
