6291-15-2 Usage
General Description
3-tert-butyl-2-hydroxy-5-methoxybenzoic acid, also known as butylated hydroxyanisole (BHA), is an antioxidant compound commonly used as a food preservative. It is a derivative of hydroxybenzoic acid and is typically synthesized from 3-tert-butyl-4-hydroxyanisole. BHA is often added to food products to prevent oxidation and rancidity, thereby extending their shelf life. It is also used in cosmetics and pharmaceuticals for its antioxidant properties. However, there is some controversy surrounding its safety, with concerns about its potential carcinogenicity and potential adverse effects on human health.
Check Digit Verification of cas no
The CAS Registry Mumber 6291-15-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,9 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6291-15:
(6*6)+(5*2)+(4*9)+(3*1)+(2*1)+(1*5)=92
92 % 10 = 2
So 6291-15-2 is a valid CAS Registry Number.

Manganese amido-imine bisphenol Hangman complexes
Yang, Jenny Y.,Nocera, Daniel G.
, p. 4796 - 4798 (2008)
A modular ligand macrocycle is composed from two phenolic groups linked to a cyclohexane bridge through an amide bond and an imine bond. The stability of the asymmetric linkers to metathesis permits a macrocyclic platform to be assembled from the condensation of two different phenolic groups in a single-step, high yield, reaction. The primary coordination sphere may be tuned with functional groups on one phenolic group. The other phenolic group may be modified with a scaffold possessing a proton transfer group. In this way, control over the secondary coordination sphere of the macrocycle is achieved. Manganese complexes of the amido-imine linked macrocycle catalytically epoxidizes 1,2-dihydronapthalene using sodium hypochlorite as the oxidant. The amido-imine macrocycles represent a new metal active site capable of supporting high oxidation states and attendant atom transfer chemistry while at the same time permitting control over the primary and secondary sphere of the metal center.
