Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2,6-Dichloro-3,4-dimethylphenoxy)acetic acid.
2-(2,6-Dichloro-3,4-dimethylphenoxy)acetic acid (CAS 19546-00-0) is a high-purity analytical reference standard with the molecular formula C10H10Cl2O3 and a molecular weight of 249.09 g/mol.
Structurally, 2-(2,6-Dichloro-3,4-dimethylphenoxy)acetic acid (C10H10Cl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 249.09 g/mol, it falls into the medium-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).
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-(2,6-Dichloro-3,4-dimethylphenoxy)acetic 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.
