1,3-Benzenedimethanol, .alpha.,.alpha.,.alpha.',.alpha.'-tetramethyl-, polymer with 1,1'-(1,1,4,4-tetramethyl-2-butyne-1,4-diyl)bis[hydroperoxide] CAS 70833-42-0

Description

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.

CATO supplies 1,3-Benzenedimethanol, .alpha.,.alpha.,.alpha.',.alpha.'-tetramethyl-, polymer with 1,1'-(1,1,4,4-tetramethyl-2-butyne-1,4-diyl)bis[hydroperoxide] (CAS 70833-42-0), a certified reference material (molecular formula C12H18O2C8H14O4, MW 368.47 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, 1,3-Benzenedimethanol, .alpha.,.alpha.,.alpha.',.alpha.'-tetramethyl-, polymer with 1,1'-(1,1,4,4-tetramethyl-2-butyne-1,4-diyl)bis[hydroperoxide] is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 368.47 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
