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 Isophthalic acid compound with nonanedioic acid and dimethyl terephthalate and 2,2-dimethylpropane-1,3-diol and ethane-1,2-diol (1:1:1:1:1).
Isophthalic acid compound with nonanedioic acid and dimethyl terephthalate and 2,2-dimethylpropane-1,3-diol and ethane-1,2-diol (1:1:1:1:1) (CAS 75701-44-9), molecular formula C10H10O4C9H16O4C8H6O4C5H12O2C2H6O2 and molecular weight 714.76 g/mol, is a CATO reference standard with documented purity and traceability.
Isophthalic acid compound with nonanedioic acid and dimethyl terephthalate and 2,2-dimethylpropane-1,3-diol and ethane-1,2-diol (1:1:1:1:1) (C10H10O4C9H16O4C8H6O4C5H12O2C2H6O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
