Chemical Structure

3,5-Bis(dodecyloxy)benzoic acid CAS 123126-40-9 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 3,5-Bis(dodecyloxy)benzoic acid.

3,5-Bis(dodecyloxy)benzoic acid (CAS 123126-40-9) is a high-purity analytical reference standard with the molecular formula C31H54O4 and a molecular weight of 490.76 g/mol.

3,5-Bis(dodecyloxy)benzoic acid (C31H54O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
