Safety Profile

Poison by intraperitoneal andintravenous routes. When heated to decomposition itemits toxic fumes of Br??.

Check Digit Verification of cas no

The CAS Registry Mumber 3785-34-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,8 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3785-34:
(6*3)+(5*7)+(4*8)+(3*5)+(2*3)+(1*4)=110
110 % 10 = 0
So 3785-34-0 is a valid CAS Registry Number.

Studies on synthesis, characterization, micellar features, and solubilization of four novel cationic gemini surfactants

Bilgen, Sel?uk,Sarikaya, Ikbal,ünver, Yasemin,Akba?, Halide

, p. 1522 - 1532 (2021)

Four novel cationic gemini surfactants with the same hydrocarbon chain lengths but different spacers have been investigated in this article. After these cationic gemini surfactants have been synthesized, their structures have been characterized by appropr

Salt, resist composition and a manufacturing method of a resist pattern

-

Paragraph 0307-0309, (2016/12/16)

PROBLEM TO BE SOLVED: To provide a resist composition from which a resist pattern with excellent pattern collapse resistance can be produced.SOLUTION: A resist pattern with excellent pattern collapse resistance can be produced by using a resist composition containing a salt expressed by formula (I) as an acid generator.

Bromoacetyl bromide: A versatile and selective cleaving agent for ethers and acetals

Schneider, David F.,Viljoen, Murray S.

, p. 721 - 728 (2007/10/03)

It is shown that bromoacetyl bromide can be utilized for the selective cleavage of ethers and acetals in high yields. With cyclic ethers and acetals as starting materials, cleavage products are produced with two strategically positioned bromo substituents which may be exploited for selective extention of the carbon chain.
