Chemical Structure
Description
CATO supplies 1,3-Diisopropylbenzene (CAS 99-62-7), a certified reference material (molecular formula C12H18, MW 162.27 g/mol) for analytical method development and quality control.
Owing to an aromatic ring system, 1,3-Diisopropylbenzene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 162.27 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).
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.
