3540-75-8 Usage
Uses
Used in Pharmaceutical Industry:
BUTYL 4-BROMOBUTYRATE is used as an intermediate in the synthesis of Bepotastine N-Butyl Ester (B317020) for its role in the production of Bepotastine, a second-generation antihistamine. Bepotastine is utilized in the treatment of allergic rhinitis and urticaria/pruritus (hives), providing relief from allergy symptoms and skin conditions.
As an intermediate in the synthesis of Bepotastine N-Butyl Ester, BUTYL 4-BROMOBUTYRATE plays a significant role in the development of medications that help alleviate the discomfort and distress caused by allergic reactions and skin irritations. Its presence in the pharmaceutical industry highlights the importance of organic compounds in the creation of effective treatments for various health conditions.
Check Digit Verification of cas no
The CAS Registry Mumber 3540-75-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,4 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3540-75:
(6*3)+(5*5)+(4*4)+(3*0)+(2*7)+(1*5)=78
78 % 10 = 8
So 3540-75-8 is a valid CAS Registry Number.

Pentamethylphenyl (Ph*) and Related Derivatives as Useful Acyl Protecting Groups for Organic Synthesis: A Preliminary Study
Cheong, Choon Boon,Frost, James R.,Donohoe, Timothy J.
supporting information, p. 1828 - 1832 (2020/10/06)
A study of acyl protecting groups derived from the Ph? motif is reported. While initial studies indicated that a variety of functional groups were not compatible with the Br 2-mediated cleavage conditions required to release the Ph? group, strategies involving the use of different reagents or a modification of Ph? itself (Ph*OH) were investigated to solve this problem.
