Chemical Structure

m-PEG5-CH2COOH CAS 16142-03-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including m-PEG5-CH2COOH.

m-PEG5-CH2COOH (CAS 16142-03-3) is a high-purity analytical reference standard with the molecular formula C13H26O8 and a molecular weight of 310.34 g/mol.

Based on its molecular formula C13H26O8, m-PEG5-CH2COOH contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 310.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.

As a certified reference material (CRM), m-PEG5-CH2COOH meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
