Chemical Structure

5-(Tert-butyl)-2-methylbenzaldehyde CAS 66949-23-3 chemical structure

Description

5-(Tert-butyl)-2-methylbenzaldehyde (CAS 66949-23-3) is a high-purity analytical reference standard with the molecular formula C12H16O and a molecular weight of 176.25 g/mol.

Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 5-(Tert-butyl)-2-methylbenzaldehyde is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 176.25 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.
