Chemical Structure

t-Butyl Methyl Fumarate CAS 55556-66-6 chemical structure

Description

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

t-Butyl Methyl Fumarate (CAS 55556-66-6) is a high-purity analytical reference standard with the molecular formula C9H14O4 and a molecular weight of 186.21 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, t-Butyl Methyl Fumarate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.21 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).

As a certified reference material (CRM), t-Butyl Methyl Fumarate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
