As OP notes, the New Testament's Βεελζεβούλ [Beelzebul] appears to come -- somehow -- from the Hebrew Bible's (Christian Old Testament's) בַּעַל זְבוּב [baʿal zĕbûb], "Lord of the flies".a Two specific questions are posed:
- Is Beelzeboul a term derived from the Hebrew Bible, and if so how?
The short answer is yes, errr, probably -- but the "how" takes a bit longer.
As Ted Lewis writes in the Anchor Bible Dictionary, having noted the NT occurrences: "Scholars have been fascinated with trying to find an etymology for this preeminent satanic being".1
There have been a welter of suggestions.2 A number of these have had only minimal support, and I won't report these below; there are two which have attracted the most sustained and widespread ... support, if not acceptance:
The HB/OT references for baʿal zĕbûb are given in the HALOT entry cited in the question, but for convenience they are: 2 Kgs 1:2, 3, 6, and 16 -- so four times in one chapter. And that's it for the HB/OT.
The translation tradition into Greek (and Syriac) knows both the -ub (Aquila) and -ul (Symmachus) versions beside the LXX's own Βααλ μυῖαν.3 When texts from ancient Ugarit were found with a reading of zbl bʿl, = "Baal" plus epithet, "Exalted Baal" or the like, then the suggestion seemed almost irresistible that the HB/OT's zebub was a denigrating substitution for zebul (cf. HALOT, sub זְבֻל II, "lofty"). An analogy might be in the substitution of ~boshet (= "shame") for ~baal in, e.g., the name "Ishbosheth" (compare NASB and NRSV at 2 Samuel 2:8).
The second suggestion ignores the zebub connection, in preference to finding a solution wholly from the HB/OT's zebul references (1 Kgs 8:13; Ps 49:15; Isa 63:15; Hab 3:11). Here, the connection is simply "Lord of Heaven", and the -ub version arises by false assimilation to the 2 Kings 1 text.
As I say, there are other explanations, but these two (or variations) are the leading contenders.
- Are there extra-biblical examples of Beelzeboul used as a synonym for Satan?
Only in the ~ούλ form. According to W. Foerster,4 it is found in Origen, Contra Celsum, VIII.25; and Hippolytus, Refutatio Omnium Haeresium, VI.34.1; also in the Testament of Solomon -- although in the latter it might not be used of Satan.5

a Note that "Baal" (or East Semitic bēl) is "lord", not "god". As it happens, Josephus, Antiquities, IX.19 has τὸν Ακκαρων θεὸν μυῖαν = "the Fly-God of Akkaron" - see Thackeray's edition (linked) for details.
