Description
As a certified reference material (CRM), 4-(Butan-2-yl)benzaldehyde 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.
4-(Butan-2-yl)benzaldehyde (CAS 28293-43-8) is a high-purity analytical reference standard with the molecular formula C11H14O and a molecular weight of 162.23 g/mol.
Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 4-(Butan-2-yl)benzaldehyde is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 162.23 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.
