4-Aminobenzoic acid (also known as para-aminobenzoic acid or PABA because the two functional groups are attached to the benzene ring across from one another in the para position) is an organic compound with the formula H 2 NC 6 H 4 CO 2 H. PABA is a white crystalline solid, [3] although commercial samples can appear gray.
The molecular formula C 7 H 7 NO 2 (molar mass: 137.14 g/mol) may refer to: Aminobenzoic acids 2-Aminobenzoic acid (o-aminobenzoic acid, anthranilic acid) 3-Aminobenzoic acid (m-aminobenzoic acid) 4-Aminobenzoic acid (p-aminobenzoic acid, PABA) Mononitrotoluenes. 2-Nitrotoluene; 3-Nitrotoluene; 4-Nitrotoluene; Salicylaldoxime; Salicylamide ...
Aminobenzoic acid (a benzoic acid with an amino group) can refer to: 4-Aminobenzoic acid (p-aminobenzoic acid or para-aminobenzoic acid) 3-Aminobenzoic acid (m ...
It also can be prepared by treating benzaldehyde under nitration conditions, a process that initially converts the aldehyde to the acid. 4-Nitrobenzoic acid is a precursor to 4-aminobenzoic acid, which is in turn used to prepare the anesthetic procaine. 4-Nitrobenzoic acid is prepared by oxidation of 4-nitrotoluene.
Padimate O is an organic compound related to the water-soluble compound PABA (4-aminobenzoic acid) that is used as an ingredient in some sunscreens. This yellowish water-insoluble oily liquid is an ester formed by the condensation of 2-ethylhexanol with dimethylaminobenzoic acid. Other names for padimate O include 2-ethylhexyl 4 ...
Just ½ cup of oats delivers 4 grams of fiber for steady blood sugar and better satiety. “Whole-grain oats are also considered a low-glycemic food,” adds Hart.
Benzocaine is the ethyl ester of p-aminobenzoic acid (PABA). It can be prepared from PABA and ethanol [29] by Fischer esterification or via the reduction of ethyl p-nitrobenzoate. Benzocaine is sparingly soluble in water; it is more soluble in dilute acids and very soluble in ethanol, chloroform, and ethyl ether.
A 52-year-old man and his dog have been stabbed to death in their own basement after an alleged intruder broke into their home, police said. The incident occurred on Monday morning at 11:42 a.m ...
