Chemical Structure

1,3-Isobenzofurandione, polymer with 2-(hydroxymethyl)-2-methyl-1,3-propanediol, 4-(1,1-dimethylethyl)benzoate nonanoate CAS 67989-21-3 chemical structure

Description

The occurrence of 1,3-Isobenzofurandione, polymer with 2-(hydroxymethyl)-2-methyl-1,3-propanediol, 4-(1,1-dimethylethyl)benzoate nonanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,3-Isobenzofurandione, polymer with 2-(hydroxymethyl)-2-methyl-1,3-propanediol, 4-(1,1-dimethylethyl)benzoate nonanoate (CAS 67989-21-3), molecular formula C25H40O5C8H4O3 and molecular weight 568.71 g/mol, is a CATO reference standard with documented purity and traceability.

1,3-Isobenzofurandione, polymer with 2-(hydroxymethyl)-2-methyl-1,3-propanediol, 4-(1,1-dimethylethyl)benzoate nonanoate (C25H40O5C8H4O3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
