Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1,1,3,5,5,5-Heptamethyl-3-((R)-2-((R)-4-methylcyclohex-3-en-1-yl)propyl)trisiloxane.
1,1,1,3,5,5,5-Heptamethyl-3-((R)-2-((R)-4-methylcyclohex-3-en-1-yl)propyl)trisiloxane (CAS 1263044-00-3), molecular formula C17H38O2Si3 and molecular weight 358.74 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1,1,1,3,5,5,5-Heptamethyl-3-((R)-2-((R)-4-methylcyclohex-3-en-1-yl)propyl)trisiloxane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.74 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.
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 1,1,1,3,5,5,5-Heptamethyl-3-((R)-2-((R)-4-methylcyclohex-3-en-1-yl)propyl)trisiloxane 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.
