Chemical Structure

Ethylene Glycol Impurity 1 (Ethylene Glycol Monoformate) CAS 628-35-3 chemical structure

Description

As a certified reference material (CRM), Ethylene Glycol Impurity 1 (Ethylene Glycol Monoformate) 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.

Ethylene Glycol Impurity 1 (Ethylene Glycol Monoformate) (CAS 628-35-3) is a high-purity analytical reference standard with the molecular formula C3H6O3 and a molecular weight of 90.08 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Ethylene Glycol Impurity 1 (Ethylene Glycol Monoformate) is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 90.08 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.
