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-Hydroxy-2,5-dimethylbenzaldehyde.
4-Hydroxy-2,5-dimethylbenzaldehyde (CAS 85231-15-8), molecular formula C9H10O2 and molecular weight 150.17 g/mol, is a CATO reference standard with documented purity and traceability.
4-Hydroxy-2,5-dimethylbenzaldehyde (C9H10O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
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.
