Ortho-Vanillin (2-Hydroxy-3-methoxybenzaldehyde) yog cov organic tseem ceeb tam sim no muaj nyob hauv cov tshuaj rho tawm thiab cov roj tseem ceeb ntawm ntau cov nroj tsuag. Nws cov pab pawg ua haujlwm suav nrog aldehyde, ether thiab phenol. ortho-Vanillin, cov sib xyaw ntawm cov mis C8H8O3, yog qhov sib txawv ntawm nws qhov isomer ntau dua, vanillin." ortho-" cov ntawv ua ntej hais txog txoj haujlwm ntawm cov sib xyaw hydroxyl moiety, uas pom muaj nyob hauv qhov chaw ua haujlwm hauv vanillin.
ortho-Vanillin yog fibrous, lub teeb daj, crystalline khoom. Tsis zoo li nws qhov zoo-paub analogue, o-vanillin tsis muaj tus yam ntxwv thiab ntxhiab tsw ntawm vanilla. Tam sim no hauv ntau yam khoom noj khoom haus, nws tsis tau tshwj xeeb nrhiav tom qab, thiab yog li ntawd tsis tshua muaj tsim thiab ntsib cov khoom noj ntxiv.
