Clear , colourless liquid · Reacts with water slowly · D at 20/4: 0,77 · B.P.: 125 °C · n20/D: 1,407 · Ign. T.: 325 °C ·
APPLICATIONS: Analytical reagent: RFE I · USP 24 · BP 2000 · Ph. Eur. III ·
Synthesis reagent: Mild silylating reagent which generates gaseous ammonia as the only by-product. Non-acidic substrates normally require a catalyst: Silylation of alcohols, including carbohydrates, is catalysed by TMS chloride . Silylation of phenols occurs readily , · The presence of TMS chloride permits the selective O-silylation of amino alcohols Synthesis 990 (1988) · Alcohols and phenols can be silylated in the presence of amines and thiols with ZnCl2 as catalyst , A range of catalysts for silylation with HMDS, including saccharin and sodium saccharin, has been recommended , for silylation of alcohols, phenols, thiols, carboxylic acids, amides, thioamides, hydroxamic acids, hydrazides, NH-groups of heterocycles, hydrazines, 1,3-diketones, etc. · The use of TBAF (0,02 eq) provides a mild procedure for O-silylation , For the preparation of volatile derivatives of a wide range of biologically active compounds for glc analysis Carbohyd |
