Chemical Structure
Description
The occurrence of Isooctyl isodecyl phthalate is closely related to a structurally diverse molecular composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Isooctyl isodecyl phthalate (CAS 42343-35-1), a certified reference material (molecular formula N/A, MW 164.11 g/mol) for analytical method development and quality control.
Isooctyl isodecyl phthalate is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).
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.
