Chemical Structure

2-Methoxyacetic anhydride CAS 19500-95-9 chemical structure

Description

The occurrence of 2-Methoxyacetic anhydride is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-Methoxyacetic anhydride (CAS 19500-95-9), a certified reference material (molecular formula C6H10O5, MW 162.14 g/mol) for analytical method development and quality control.

Structurally, 2-Methoxyacetic anhydride (C6H10O5) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 162.14 g/mol, it falls into the medium-molecular-weight range.

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), 2-Methoxyacetic anhydride 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.
