Chemical Structure

1,5-Dichlorohexamethyltrisiloxane CAS 3582-71-6 chemical structure

Description

1,5-Dichlorohexamethyltrisiloxane (CAS 3582-71-6), molecular formula C6H18Cl2O2Si3 and molecular weight 277.37 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H18Cl2O2Si3, 1,5-Dichlorohexamethyltrisiloxane contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 277.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 1,5-Dichlorohexamethyltrisiloxane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
