Chemical Structure

4-Mesitylbutanal CAS 166947-18-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Mesitylbutanal.

4-Mesitylbutanal (CAS 166947-18-8), molecular formula C13H18O and molecular weight 190.28 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 4-Mesitylbutanal is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 190.28 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.

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.
