Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,3,2-Dioxaphosphorinane, 5,5-dimethyl-2-(2,4,6-trimethylphenoxy)-, 2-oxide (CAS 72018-09-8), molecular formula C14H21O4P and molecular weight 284.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 1,3,2-Dioxaphosphorinane, 5,5-dimethyl-2-(2,4,6-trimethylphenoxy)-, 2-oxide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.29 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).
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.
