3550-43-4 Usage
Uses
Used in Cosmetic and Skincare Industry:
2-hydroxyhept-4-oxybenzophenone is used as a UV filter for its ability to absorb ultraviolet radiation. This application is crucial in various sunscreen formulations, where it serves to protect the skin from the harmful effects of UV rays. However, it is important to note that some experimental studies have indicated the potential for 2-hydroxyhept-4-oxybenzophenone to act as an endocrine disruptor. As a result, further research is necessary to fully understand its safety profile for both humans and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 3550-43-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,5 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3550-43:
(6*3)+(5*5)+(4*5)+(3*0)+(2*4)+(1*3)=74
74 % 10 = 4
So 3550-43-4 is a valid CAS Registry Number.

Synthese von 4-Alkoxy-2-hydroxyphenylketoximen als Metallextraktions-Reagenzien

The C-Acylation (Friedel-Crafts reaction) of resorcinol with aluminium chloride, the monoetherification in 4-position of the resulting 2,4-dihydroxyphenylketones, and the preparation of oximes (8, 9, 10, 11) from this ketones were investigated.The compounds obtained are characterized by elemental analysis, and the i.r., u.v. and 1H-n.m.r. spectra are discussed.Solubility data of some oximes are determined in water, octane and toluene.The extraction properties for copper-(II)-and iron-(III)-ions are measured by isotope methods in relation to the extragent structure, the extraction time and the pH-range.
