Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,3'-(1,1,3,3-Tetramethyldisiloxane-1,3-diyl)bis(propan-1-ol).
3,3'-(1,1,3,3-Tetramethyldisiloxane-1,3-diyl)bis(propan-1-ol) (CAS 18001-97-3), molecular formula C10H26O3Si2 and molecular weight 250.48 g/mol, is a CATO reference standard with documented purity and traceability.
3,3'-(1,1,3,3-Tetramethyldisiloxane-1,3-diyl)bis(propan-1-ol) (C10H26O3Si2) 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(propan-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.
