189756-89-6 Usage
General Description
4-Bromo-[1,2]oxathiolane 2,2-dioxide is a synthetic compound also known as bronopol. It is used as a preservative in various industrial and consumer products such as personal care products, cosmetics, and household cleaners. Bronopol has antimicrobial properties that inhibit the growth of bacteria, fungi, and other microorganisms, making it an effective preservative for preventing spoilage and contamination. However, it has been associated with allergic contact dermatitis in some individuals and is considered a potential skin sensitizer. Additionally, there have been concerns about bronopol's potential to release formaldehyde, a known carcinogen, when it reacts with other chemicals. As a result, there have been restrictions and bans on the use of bronopol in certain countries and industries.
Check Digit Verification of cas no
The CAS Registry Mumber 189756-89-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,7,5 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 189756-89:
(8*1)+(7*8)+(6*9)+(5*7)+(4*5)+(3*6)+(2*8)+(1*9)=216
216 % 10 = 6
So 189756-89-6 is a valid CAS Registry Number.

Synthesis and Diels-Alder reactions of prop-1-ene-1,3-sultone, and chemical transformations of the Diels-Alder adducts
Jiang, La Sheng,Chan, Wing Hong,Lee, Albert W. M.
, p. 2245 - 2262 (2007/10/03)
A reliable and novel synthetic route for the preparation of prop-1-ene- 1,3-sultone (1) has been developed. An overall yield of 34% could be achieved for this five-step synthesis. The Diels-Alder reactions of 1 with a variety of dienes were investigated for the first time and achieved with good chemical yield and excellent endo-selectivity. The subsequent transformations of the Diels-Alder cycloadducts were also explored.
