The "10" is the ball diameter in millimeters. The "3000" is the force in kilograms force. The hardness may also be shown as XXX HB YYD 2. The XXX is the force to apply (in kgf) on a material of type YY (5 for aluminum alloys, 10 for copper alloys, 30 for steels). Thus a typical steel hardness could be written: 250 HB 30D 2. It could be a ...
(1E,2Z)-3-hydroxy-5,9,17-trioxo-4,5:9,10-disecoandrosta-1(10),2-dien-4-oate + H 2 O 3-[(3aS,4S,7aS)-7a-methyl-1,5-dioxo-octahydro-1H-inden-4-yl]propanoate + (2Z,4Z)-2-hydroxyhexa-2,4-dienoate The enzyme is involved in the bacterial degradation of the steroid ring structure.

It was developed in the late 1940s, synthesized by reaction of 2,4,5-Trichlorophenol and chloroacetic acid. It was widely used in the agricultural industry until being phased out ...
1,2,4,5-tetrachlorobenzene once was used as intermediates in the production of pesicides, [3] specifically trichlorophenols. This method has been discontinued because it also produced 2,3,7,8-tetrachlorodibenzo-p- dioxin .
2,4-DB or 4- (2,4-dichlorophenoxy)butyric acid is a selective systemic phenoxy herbicide used to control many annual and perennial broad-leaf weeds in alfalfa, peanuts, soybeans, and other crops. Its active metabolite, 2,4-D, inhibits growth at the tips of stems and roots. It is classified in toxicity class III.
Infobox references. 2,5-Bis (hydroxymethyl)furan ( BHMF) is a heterocyclic organic compound, and is a derivative of a broader class of compounds known as furans. It is produced from cellulose and has received attention as a biofeedstock. [3] It is a white solid, although commercial samples can appear yellowish or tan.
