Chemical Structure

Disiloxane, 1,3-diethenyl-1,1,3,3-tetramethyl-, polymer with 1,1,3,3-tetramethyldisiloxane CAS 68015-65-6 chemical structure

Description

CATO manufactures Disiloxane, 1,3-diethenyl-1,1,3,3-tetramethyl-, polymer with 1,1,3,3-tetramethyldisiloxane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

Disiloxane, 1,3-diethenyl-1,1,3,3-tetramethyl-, polymer with 1,1,3,3-tetramethyldisiloxane (CAS 68015-65-6) is a high-purity analytical reference standard with the molecular formula C8H18OSi2C4H12OSi2 and a molecular weight of 318.71 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Disiloxane, 1,3-diethenyl-1,1,3,3-tetramethyl-, polymer with 1,1,3,3-tetramethyldisiloxane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
