Abstract
The present invention provides the following [1] to [3], etc. [1] 1,3-Butylene glycol where, in a gas chromatographic analysis under a specific condition, the sum of area values of peaks appearing during the specific relative retention time to the area value of the peak of 1,3-butylene glycol is not more than 0.025%. [2] 1,3-Butylene glycol where, in a gas chromatographic analysis under a specific condition, the sum of area values of peaks of compounds having a hydroxyl group and an ether bond and having a molecular weight of 188 to the area value of the peak of 1,3-butylene glycol is not more than 0.025%. [3] 1,3-Butylene glycol where, in a gas chromatographic analysis under a specific condition, the sum of area values of peaks of 2-butoxy-6-methyl-4-tetrahydropyranol to the area value of the peak of 1,3-butylene glycol is not more than 0.025%.
