Chemical Structure

trans,trans-Muconic Acid CAS 3588-17-8 chemical structure

Description

trans,trans-Muconic Acid (CAS 3588-17-8), molecular formula C6H6O4 and molecular weight 142.11 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, trans,trans-Muconic Acid is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.11 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).

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.
