1,3-butylene glycol product

A 1,3-butylene glycol product, having, according to a gas chromatographic analysis performed under conditions set forth below:

• 1000 ppm or lower of an area ratio of a peak appearing in a relative retention time ranging from 2.3 to 2.4, provided that the relative retention time for a peak of 1,3-butylene glycol is 1.0,
