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.
TOLUENE-4-SULFONIC ACID 2,2,5-TRIMETHYL-[1,3]DIOXAN-5-YLMETHYL ESTER (CAS 34541-77-0) is a high-purity analytical reference standard with the molecular formula C7H8O3SC8H16O3 and a molecular weight of 332.41 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, TOLUENE-4-SULFONIC ACID 2,2,5-TRIMETHYL-[1,3]DIOXAN-5-YLMETHYL ESTER is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 332.41 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.
