Chemical Structure

Acid Red 52 CAS 3520-42-1 chemical structure

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.

Acid Red 52 (CAS 3520-42-1) is a high-purity analytical reference standard with the molecular formula C27H29N2O7S2Na and a molecular weight of 580.65 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Acid Red 52 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 580.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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