5-Isobenzofurancarboxylic acid, 1,3-dihydro-1,3-dioxo-, polymer with 4,4'-(1-methylethylidene)bis[phenol] and 2-(phenoxymethyl)oxirane CAS 73050-14-3

Description

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.

CATO supplies 5-Isobenzofurancarboxylic acid, 1,3-dihydro-1,3-dioxo-, polymer with 4,4'-(1-methylethylidene)bis[phenol] and 2-(phenoxymethyl)oxirane (CAS 73050-14-3), a certified reference material (molecular formula C15H16O2C9H4O5C9H10O2, MW 570.59 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 5-Isobenzofurancarboxylic acid, 1,3-dihydro-1,3-dioxo-, polymer with 4,4'-(1-methylethylidene)bis[phenol] and 2-(phenoxymethyl)oxirane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 570.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
