Chemical Structure

3,3'-(1,1,3,3-Tetramethyldisiloxane-1,3-diyl)bis(2-methylpropan-1-ol) CAS 29706-30-7 chemical structure

Description

The occurrence of 3,3'-(1,1,3,3-Tetramethyldisiloxane-1,3-diyl)bis(2-methylpropan-1-ol) is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3,3'-(1,1,3,3-Tetramethyldisiloxane-1,3-diyl)bis(2-methylpropan-1-ol) (CAS 29706-30-7), a certified reference material (molecular formula C12H30O3Si2, MW 278.54 g/mol) for analytical method development and quality control.

3,3'-(1,1,3,3-Tetramethyldisiloxane-1,3-diyl)bis(2-methylpropan-1-ol) (C12H30O3Si2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 3,3'-(1,1,3,3-Tetramethyldisiloxane-1,3-diyl)bis(2-methylpropan-1-ol) 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.
