Chemical Structure

Aluminumbenzoate CAS 555-32-8 chemical structure

Description

Aluminumbenzoate (CAS 555-32-8), molecular formula C7H5O2Al and molecular weight 148.10 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Aluminumbenzoate is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.10 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.

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.
