Chemical Structure

Bis-PEG3-t-butyl ester CAS 1611468-29-1 chemical structure

Description

The occurrence of Bis-PEG3-t-butyl ester is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Bis-PEG3-t-butyl ester (CAS 1611468-29-1), molecular formula C18H34O7 and molecular weight 362.46 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Bis-PEG3-t-butyl ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 362.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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), Bis-PEG3-t-butyl ester 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.
