Chemical Structure

3-Methyl-3-(m-tolyl)butanoic acid CAS 19355-31-8 chemical structure

Description

CATO manufactures 3-Methyl-3-(m-tolyl)butanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

3-Methyl-3-(m-tolyl)butanoic acid (CAS 19355-31-8) is a high-purity analytical reference standard with the molecular formula C12H16O2 and a molecular weight of 192.25 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 3-Methyl-3-(m-tolyl)butanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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