Chemical Structure
Description
3-(1,1-DIMETHYLETHYL)-4-HYDROXY-5-METHOXY-BENZALDEHYDE (CAS 33837-83-1) is a high-purity analytical reference standard with the molecular formula C12H16O3 and a molecular weight of 208.25 g/mol.
3-(1,1-DIMETHYLETHYL)-4-HYDROXY-5-METHOXY-BENZALDEHYDE (C12H16O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 3-(1,1-DIMETHYLETHYL)-4-HYDROXY-5-METHOXY-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.
