75-79-6 UIR5I18638 Methyltrichlorosilane Silane, methyltrichloro- Silane, trichloromethyl- Trichloro(methyl)silane 4-04-00-04212 (Beilstein Handbook Reference) AI3-51465 BRN 1361381 CCRIS 1322 EINECS 200-902-6 HSDB 840 Methylsilicochloroform Methylsilyl trichloride Methyl-trichlorsilan [Czech] Monomethyltrichlorosilane NSC 77069 Trichlor-methylsilan [Czech] Trichloromethylsilane Trichloromethylsilicon Methyl-trichlorsilan Trichlor-methylsilan UNII-UIR5I18638 EC 200-902-6 Methyltrichlorosilane [UN1250] [Flammable liquid] UN1250 (CAS 75-79-6) is a high-purity analytical reference standard with the molecular formula CH3Cl3Si and a molecular weight of 149.48 g/mol.
The molecular framework of 75-79-6 UIR5I18638 Methyltrichlorosilane Silane, methyltrichloro- Silane, trichloromethyl- Trichloro(methyl)silane 4-04-00-04212 (Beilstein Handbook Reference) AI3-51465 BRN 1361381 CCRIS 1322 EINECS 200-902-6 HSDB 840 Methylsilicochloroform Methylsilyl trichloride Methyl-trichlorsilan [Czech] Monomethyltrichlorosilane NSC 77069 Trichlor-methylsilan [Czech] Trichloromethylsilane Trichloromethylsilicon Methyl-trichlorsilan Trichlor-methylsilan UNII-UIR5I18638 EC 200-902-6 Methyltrichlorosilane [UN1250] [Flammable liquid] UN1250 (CH3Cl3Si) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
