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-(3,4-Dichloro-benzyloxymethyl)-6-methoxy-benzoic acid methyl ester.
2-(3,4-Dichloro-benzyloxymethyl)-6-methoxy-benzoic acid methyl ester (CAS 1171923-68-4), molecular formula C17H16Cl2O4 and molecular weight 355.21 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(3,4-Dichloro-benzyloxymethyl)-6-methoxy-benzoic acid methyl ester (C17H16Cl2O4) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 355.21 g/mol, it falls into the moderately-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).
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.
CATO manufactures 2-(3,4-Dichloro-benzyloxymethyl)-6-methoxy-benzoic acid methyl ester under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
