> The alt-right, or alternative right, is a loosely connected and somewhat ill-defined grouping of American white supremacists/white nationalists, white separatists, anti-Semites, neo-Nazis, neo-fascists, neo-Confederates, Holocaust deniers, conspiracy theorists and other far-right fringe hate groups.
I don't see how Peterson fits in that category. In a way the fact that the term is abused by the left to refer to all sort of non extremist people seems to have given a new meaning that you are refering to. Kind of like far-left movements refering to "facists" anyone to their right in the 80s.
And being an opponent of some of the more ludicrous off-shoots of modern feminism is not "alt-right", it's just common sense (and mainstream: for example only 9% of women in the UK consider themselves feminist[1]). And science, etc. Now I don't necessarily agree with his stances, but they are nothing if not well-reasoned and supported by data.
Which is probably why he gets so much hate.

Is this not him being a proponent of "race science"?
Anyway, since you are making the claim, it would be up to you to explain what in his words is "promoting" (what a proponent does) so-called "race-science".
First, you'd probably have to define what you mean with "race science".
No, "alt-right" is people who haven't gone "far-right" (yet) or who are hiding their "far-right"ness for an easier life / speaking gigs / patreon money / etc.

He certainly pals around with a lot of alt-right figures (Tucker Carlson, notably) and seems to have no problem appearing at Turning Point USA’s Student Action Summit which has quite the strongly conservative/alt-right/far-right[1] list of speakers.
