Triisopropylsilyl fluoride (TIPS-F) is an organosilicon reagent with the chemical formula (C3H7)3SiF. It is a colorless, volatile liquid that is widely used in organic synthesis as a protecting group for hydroxyl groups. TIPS-F is known for its stability, selectivity, and ease of removal, making it a popular choice for protecting alcohols and phenols in various chemical reactions. The bulky isopropyl groups attached to the silicon atom provide steric hindrance, which helps to prevent unwanted side reactions and ensures the selective protection of the desired functional groups. TIPS-F is also used in the synthesis of various silyl ethers, which are important intermediates in the preparation of pharmaceuticals, agrochemicals, and other specialty chemicals.

426-67-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 426-67-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 426-67:
(5*4)+(4*2)+(3*6)+(2*6)+(1*7)=65
65 % 10 = 5
So 426-67-5 is a valid CAS Registry Number.

A naphthalimide-based highly selective colorimetric and ratiometric fluorescent probe for the fluoride ion displayed both one-and two-photon ratiometric changes. Upon reaction with the F- (TBA+ and Na+ salts) anion in CHs

Kinetics of self-immolation: Faster signal relay over a longer linear distance?

Lee, Ho Yong,Jiang, Xuan,Lee, Dongwhan

supporting information; experimental part, p. 2065 - 2068 (2009/10/10)

A counterintuitive observation of a faster signal relay over a longer linear distance prompted detailed kinetic studies of self-immolation reactions. With appropriate conformational bias, trigger-to-reporter signal transduction can take an efficient "shor

THIOLS, UNSYMMETRICAL SULFIDES AND THIOACETALS FROM THE NEW REAGENT: TRIISOPROPYLSILANETHIOL

Miranda, Edgar I.,Diaz, Michael J.,Rosado, Izander,Soderquist, John A.

, p. 3221 - 3224 (2007/10/02)

Triisopropylsilanethiol (HSTIPS, 1), easily prepared in 98percent yield from H2S and TIPSCl, is efficiently alkylated in a selective manner with 10 and 20 alkyl halides or tosylates through its potassium thiolate (2c) to provide RSTIPS (3) in excellent yields.Compound 3 provides a convenient source of alkanethiols (4), unsymmetrical dialkyl sulfides (5) and thioacetals (6).
