Yes. Clavulanate potassium is hygroscopic and degrades with moisture and heat, so send it sealed and dry; its breakdown products separate by HPLC.
No. The $250 test covers identity, purity and quantity against a reference standard. Full testing to the USP Clavulanate Potassium monograph adds the monograph's own tests and is quoted.
USP monographs also exist for these clavulanate titles. The $250 identity, purity and quantity test applies to each; testing to the monograph for any of them is available and quoted. Tell us the title your specification names.
