Chemical Structure

TCO-PEG3-acid CAS 2141981-86-2 chemical structure

Description

TCO-PEG3-acid (CAS 2141981-86-2) is a high-purity analytical reference standard with the molecular formula C18H31NO7 and a molecular weight of 373.44 g/mol.

The molecular framework of TCO-PEG3-acid (C18H31NO7) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), TCO-PEG3-acid 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.
