3-(3-Chloropropyl)-1,1,1,5,5,5-hexamethyl-3-((trimethylsilyl)oxy)trisiloxane CAS 18077-31-1

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.

3-(3-Chloropropyl)-1,1,1,5,5,5-hexamethyl-3-((trimethylsilyl)oxy)trisiloxane (CAS 18077-31-1), molecular formula C12H33ClO3Si4 and molecular weight 373.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(3-Chloropropyl)-1,1,1,5,5,5-hexamethyl-3-((trimethylsilyl)oxy)trisiloxane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 373.18 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.

CATO manufactures 3-(3-Chloropropyl)-1,1,1,5,5,5-hexamethyl-3-((trimethylsilyl)oxy)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.
