I’m fairly certain the source you used made an error (but, like you say, I’m not a chemist either)…Though I believe it’s correct until the italics.

The Propylene Glycol 57-55-6 is "1,2-propanediol”, otherwise known as PDO.

PG = 1,2
PDO = 1,3

The compound is sometimes called α-propylene glycol to distinguish it from the isomer propane-1,3-diol (β-propylene glycol).

One molecule difference…is it any wonder us “normal folks” get confused easily?

Propylene glycol (IUPAC name: propane-1,2-diol) is a synthetic organic compound with the chemical formula C3H8O2

1,3-Propanediol is the organic compound with the formula CH2(CH2OH)2
