41. The chemical structure was initially characterized through a combination of hexahydroazepane, and 4-hydroxy benzoyl moiety. 42. Anyway, benzoic acid can also be conjugated to things as a benzoate, i . e . benzoyl . 43. -Apply over-the-counter products such as benzoyl peroxide ( use once or twice a day ). 44. Current information from Pillsbury is that their varieties of bleached flour are treated both with benzoyl peroxide and chlorine gas. 45. Topical dapsone is not recommended for use with benzoyl peroxide due to yellow-orange skin discoloration with this combination. 46. A more recent synthesis, providing a better yield, is by the reduction of benzoyl cyanide using LiAlH 4. 47. One of the newer topical medications, Benzamycin, combines benzoyl peroxide, an antibacterial, with erythromycin, an antibiotic. 48. In a 1977 study using a human maximization test, 76 % of subjects acquired a contact sensitization to benzoyl peroxide. 49. Next, a chemical bleaching process with chlorine or benzoyl peroxide is used, to give the flour a whiter color. 50. It is possible to use benzoyl chloride but the yields and regioselectivity of the addition of the cyano group are lower.
