423-50-7 Usage
Uses
Used in Chemical Production Industry:
Perfluorohexane sulphonyl fluoride is used as a fluorinating agent for the synthesis of fluorochemical derivatives and surfactants, due to its stability and low reactivity.
Used in Industrial Applications:
Perfluorohexane sulphonyl fluoride is used as an intermediate in the synthesis of fluorinated molecules, contributing to the development of various industrial products.
However, it is important to note that the same properties that make PFHSF suitable for industrial use also contribute to its persistence and bioaccumulation in the environment. This raises concerns about its potential impacts on human health and the environment. Long-term exposure to PFHSF can lead to adverse human health risks, such as endocrine disruption, cancer, and potential developmental and reproductive toxicity. Additionally, its presence has been detected in water systems and wildlife, indicating its extensive distribution and persistence.
Check Digit Verification of cas no
The CAS Registry Mumber 423-50-7 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 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 423-50:
(5*4)+(4*2)+(3*3)+(2*5)+(1*0)=47
47 % 10 = 7
So 423-50-7 is a valid CAS Registry Number.

A new synthetic procedure for the preparation of perfluoroalkanesulfonyl fluorides utilizing liquid-phase direct fluorination with elemental fluorine has been developed. Direct fluorination of a partially fluorinated ester, which has alkanesulfonyl fluoride in the end, was synthesized from non-fluorinated counterparts and perfluorinated acid fluoride according to the PERFECT process, gave the desired perfluorinated product in moderate yield as well as by-products arising from CS bond cleavage. The results of the direct fluorination of some model substrates suggest that the CS bond cleavage occurred due to radical formation at the α-position rather than the β-position.
