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 Diglycolic anhydride Diglycolic acid anhydride Oxydiacetic anhydride p-Dioxane-2,6-dione 1,4-Dioxane-2,6-dione 4480-83-5.
CATO supplies Diglycolic anhydride Diglycolic acid anhydride Oxydiacetic anhydride p-Dioxane-2,6-dione 1,4-Dioxane-2,6-dione 4480-83-5 (CAS 4480-83-5), a certified reference material (molecular formula C4H4O4, MW 116.07 g/mol) for analytical method development and quality control.
The molecular framework of Diglycolic anhydride Diglycolic acid anhydride Oxydiacetic anhydride p-Dioxane-2,6-dione 1,4-Dioxane-2,6-dione 4480-83-5 (C4H4O4) is characterized by a carbohydrate-derived structure. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Diglycolic anhydride Diglycolic acid anhydride Oxydiacetic anhydride p-Dioxane-2,6-dione 1,4-Dioxane-2,6-dione 4480-83-5 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.
