At present, the most significant of these is the two-step process practiced by Rhodia since the 1970s, in which guaiacol (1) reacts with glyoxylic acid by electrophilic aromatic substitution. [39] The resulting vanillylmandelic acid (2) is then converted by 4-Hydroxy-3-methoxyphenylglyoxylic acid (3) to vanillin (4) by oxidative decarboxylation ...
ortho-Vanillin (2-hydroxy-3-methoxybenzaldehyde) is an organic solid present in the extracts and essential oils of many plants. [1] [2] [3] Its functional groups include aldehyde, ether and phenol. ortho-Vanillin, a compound of the formula C 8 H 8 O 3, is distinctly different from its more prevalent isomer, para-vanillin.
4-Hydroxy-3-methoxybenzyl alcohol ... CAS Number. 498-00-0 ... Chemical formula. C 8 H 10 O 3: Molar mass: 154.165 g·mol −1 Appearance
4‑Hydroxybenzaldehyde (para‑hydroxybenzaldehyde) is an organic compound with the formula C 6 H 4 OH(CHO). [4] [5] Along with 2-hydroxybenzaldehyde and 3-hydroxybenzaldehyde, it is one of the three isomers of hydroxybenzaldehyde.
The nitrile obtained reacts with a hydroxamic acid chloride to give a 3,5-disubstituted 1,2,4-oxadiazole as a further intermediate. Intermediate in the opicapon synthesis With hydrazides , the aldehyde 5-nitrovanillin forms hydrazones that can be cyclized with Chloramine-T to give substituted 1,3,4-oxadiazoles.
It has the identical chemical formula with the methoxy group (−O−CH 3) that differs only in the attachment site and orientation to the rest of the molecule. However, their chemical properties are different. [1] [2] Hydroxymethyl is the side chain of encoded amino acid serine. [3]
3,4,5-Trimethoxybenzaldehyde can be used as an intermediate in the synthesis of some pharmaceutical drugs including trimethoprim, [1] [2] cintriamide, roletamide, trimethoquinol (aka tretoquinol), and trimazosin as well as some psychedelic phenethylamines.
3-Hydroxybenzaldehyde is an organic compound with the formula HOC 6 H 4 CHO. It is a colorless solid although most samples appear tan. It is a colorless solid although most samples appear tan. Two other isomers of hydroxybenzaldehyde exist.
