ACS grade is the highest level of purity, and meets the standards set by the American Chemical Society (ACS). The official descriptions of the ACS levels of purity is documented in the Reagent Chemicals publication, issued by the ACS. [3] [4] It is suitable for food and laboratory uses. Reagent grade is almost as stringent as the ACS grade.
Chemicals that meet this standard may be sold as "ACS Reagent Grade" materials. Reagent standards relieve chemists of concern over chemical purity. "ACS Reagent Grade", is regarded as a gold standard measure and is in some cases required for use in chemical manufacturing, usually where stringent quality specifications and a purity of equal to ...
APHA color, also referred to as the Hazen scale, and more appropriately as the Platinum Cobalt(Pt/Co) scale, [1] is a color standard named for the American Public Health Association and defined by ASTM D1209. [2] It was originally intended to describe the color of waste water, but its usage has expanded to include other industrial applications ...
In 1874, a group of American chemists gathered at the Joseph Priestley House to mark the 100th anniversary of Priestley's discovery of oxygen.Although there was an American scientific society at that time (the American Association for the Advancement of Science, founded in 1848), the growth of chemistry in the U.S. prompted those assembled to consider founding a new society that would focus ...
Organic Letters is a biweekly peer-reviewed scientific journal covering research in organic chemistry. It was established in 1999 and is published by the American Chemical Society. In 2014, the journal moved to a hybrid open access publishing model. The founding editor-in-chief was Amos Smith. The current editor-in-chief is Marisa C. Kozlowski. [1]
The Journal of Chemical Education is a monthly peer-reviewed academic journal available in both print and electronic versions. It is published by the Division of Chemical Education of the American Chemical Society and was established in 1924 by Neil Gordon. [1]
The tert-butyloxycarbonyl protecting group or tert-butoxycarbonyl protecting group [1] (BOC group) is an acid-labile protecting group used in organic synthesis. The BOC group can be added to amines under aqueous conditions using di- tert -butyl dicarbonate in the presence of a base such as sodium hydroxide :
The journal has absorbed two other publications in its history, the Journal of Analytical and Applied Chemistry (July 1893) and the American Chemical Journal (January 1914). It covers all fields of chemistry. Since 2021, the editor-in-chief is Erick M. Carreira . [2] In 2014, the journal moved to a hybrid open access publishing model.
