Chemical Structure

Diethylene glycol ethyl methyl ether CAS 1002-67-1 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 Diethylene glycol ethyl methyl ether.

Diethylene glycol ethyl methyl ether (CAS 1002-67-1), molecular formula C7H16O3 and molecular weight 148.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Diethylene glycol ethyl methyl ether (C7H16O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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), Diethylene glycol ethyl methyl ether 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.
