3550-43-4 Usage
General Description
2-Hydroxyhept-4-enoylbenzophenone, also known as "2HHOB" or "4’-(2-Hydroxy-4’-hepta-2′,4′-dienylphenyl)-phenylmethanone" is a synthetic chemical compound. This organic compound is predominantly used in the cosmetic and skincare industry due to its UV-absorbing capabilities, thus functioning as a UV filter in various sunscreen formulations to protect skin from harmful ultraviolet radiations. Despite its widespread use, some experimental studies have suggested that it may be an endocrine disruptor, warranting further research to evaluate its safety to 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
Beger, J.,Binte, H.-J.,Brunne, L.,Neumann, R.
, p. 269 - 277 (2007/10/02)
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.
