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 2,2'-((4-Methyl-1,2-phenylene)bis(oxy))diacetic acid.
CATO supplies 2,2'-((4-Methyl-1,2-phenylene)bis(oxy))diacetic acid (CAS 5458-76-4), a certified reference material (molecular formula C22H28O3C21H26O2, MW 650.90 g/mol) for analytical method development and quality control.
Structurally, 2,2'-((4-Methyl-1,2-phenylene)bis(oxy))diacetic acid (C22H28O3C21H26O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 650.90 g/mol, it falls into the high-molecular-weight range. 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).
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), 2,2'-((4-Methyl-1,2-phenylene)bis(oxy))diacetic 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.
