You are fighting on two fronts: first, in the academia, and second, on the job market.
About the job market:
In the eyes of the job market, you are now a beginner on the job market with a chemistry BSc.
First, employers are interested mainly only in the papers what you can show, and about a "real", ready degree.
"I've nearly made a Phd" may be more than nothing, but not too much.
The reason, why have you a hard time now, is that the degree are often an "nothing or everything" game: until you don't have your real Phd in your hands, you have nothing. It is in inherent unfairness or the world, however this world is also on the continuous, massive "assault" of the fake papers, and low-value papers which were produced by zero-to-little work behind, and so on.
But, the most important to know: the main reason of your hard time on the job market is not this. The real reason is that you are a beginner. To get employed to your first job is always hard, often very, very hard. I would suggest, to get your first job, you are simply not in the position where you could select between the offers.
There is also the option to switch to IT world. The sad truth is that in most countries, there is far lesser jobs as scientist, as many people get their science degree, particularly if it is not a high-value one. To get a work as a chemist is not easy even with a Phd from chemistry.
In the IT, the situation is significantly different: many people is working in the IT world with no or low-value degrees. Furthermore, the IT is working so that hardcore math and your University doesn't help very much to solve practical problems.
About the academia:
As you said, you have no very long-term goals in this world, your original plan was to get the Phd and then work in the industry. You can see your options in the job market now, this is what could determine, what you do in the academia.
Young people typically tend to over-estimate the worth of some "lost" years, in practice, 20 years later (from which you wasted 5...15 on crap jobs), you will see that with different eyes. It depends on your current age and financial options.
If you have the potential to get to a Phd, do it on all the costs. Years, risks, hard fights, hard work, these all don't matter, you want the Phd and you will get it. This is the only possible attitude on the way to your so wanted degree.
If you don't, then this is not an option. Most likely you won't be able to work as scientist with a BSc (here are large differences between the countries, so you may have luck).
