p-Anisic acid, also known as 4-methoxybenzoic acid or draconic acid, is one of the isomers of anisic acid. The term "anisic acid" often refers to this form specifically. [ 1 ] It is a white crystalline solid which is insoluble in water, highly soluble in alcohols, and soluble in ether and ethyl acetate .
Anisic acid or methoxybenzoic acid is an organic compound which is a carboxylic acid. It exists in three forms, depending on arene substitution patterns: p-Anisic acid (4-methoxybenzoic acid) m-Anisic acid (3-methoxybenzoic acid) o-Anisic acid (2-methoxybenzoic acid)
Nitric acid, with a pK value of around −1.7, behaves as a strong acid in aqueous solutions with a pH greater than 1. [23] At lower pH values it behaves as a weak acid. pK a values for strong acids have been estimated by theoretical means. [24] For example, the pK a value of aqueous HCl has been estimated as −9.3.
The molecular formula C 8 H 8 O 3 (molar mass: 152.15 g/mol) may refer to: . Anisic acids. o-Anisic acid (2-methoxybenzoic acid); m-Anisic acid (3-methoxybenzoic acid); p-Anisic acid (4-methoxybenzoic acid)
See Amino acid for the pK a values of all amino acid side chains inferred in such a way. There are also numerous experimental studies that have yielded such values, for example by use of NMR spectroscopy. The table below lists the model pK a values that are often used in a protein pK a calculation, and contains a third column based on protein ...

Stock Performance is the difference between a director's stock index and the S&P 500. A director's stock index is an unweighted index of company stock performances while they sat on the board. CEO pay includes salary, bonuses, stock sales, and other payments. Average CEO Pay is calculated using the last year a director sat on the board of each ...
Methyl anisate is the methyl ester of p-anisic acid. It is found in star anise. It is an organic compound commonly used within the food industry. It is also commonly employed as a fragrance for certain perfumes. This compound can be synthesized directly through the condensation of methanol and 4-methoxybenzoic acid.
