76782-82-6 A838826 tert-butyl-dimethyl-prop-2-ynoxy-silane tert-butyl-dimethyl-prop-2-ynoxysilane CAS 76782-82-6 chemical structure

Description

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.

76782-82-6 A838826 tert-butyl-dimethyl-prop-2-ynoxy-silane tert-butyl-dimethyl-prop-2-ynoxysilane (CAS 76782-82-6) is a high-purity analytical reference standard with the molecular formula C9H18OSi and a molecular weight of 170.32 g/mol.

Owing to a hydroxyl group, an ether linkage, 76782-82-6 A838826 tert-butyl-dimethyl-prop-2-ynoxy-silane tert-butyl-dimethyl-prop-2-ynoxysilane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
