ITEM 4.01    Change in Registrant's Certifying Accountant

(a)     Previous Independent Accountant

        On November 23, 2005, the Audit Committee of the Board of Directors
        ("Audit Committee") of Aceto Corporation (the "Company") dismissed KPMG
        LLP ("KPMG") as the Company's independent registered public accounting
        firm. The decision to change accountants was made unanimously by the
        Company's Audit Committee.

        The audit reports of KPMG on the Company's financial statements for the
        past two fiscal years did not contain an adverse opinion or a disclaimer
        of opinion and were not qualified or modified as to uncertainty, audit
        scope or accounting principle. The audit report of KPMG on management's
        assessment of the effectiveness of internal control over financial
        reporting and the effectiveness of internal control over financial
        reporting as of June 30, 2005 did not contain an adverse opinion or
        disclaimer of opinion, and was not qualified or modified as to
        uncertainty, audit scope or accounting principles. During the two most
        recent fiscal years and through November 23, 2005, there have been no
        disagreements with KPMG on any matter of accounting principles or
        practices, financial statement disclosures, or auditing scope or
        procedures, which disagreements, if not resolved to the satisfaction of
        KPMG, would have caused KPMG to make reference to the subject matter of
        the disagreement in connection with its reports on the financial
        statements for such periods. During the two most recent fiscal years and
        through November 23, 2005, there have been no reportable events as
        defined in Item 304(a)(1)(v) of Regulation S-K.

        The Company has provided KPMG with a copy of this Form 8-K and requested
        that KPMG furnish it with a letter addressed to the Securities and
        Exchange Commission stating whether it agrees with the statements made
        by the Company herein and, if not, stating the respects in which it does
        not agree. A letter from KPMG, dated as of November 29, 2005 regarding
        its concurrence with these statements is attached hereto as Exhibit
        16.1.
 
(b)     New Independent Accountant

        On November 23, 2005, the Audit Committee unanimously voted to engage
        BDO Seidman, LLP ("BDO") as its independent registered public accounting
        firm to audit the Company's financial statements and internal control
        over financial reporting as of and for the year ending June 30, 2006.
 
        The Company did not consult with BDO during the two most recent fiscal
        years and through November 23, 2005 regarding either the application of
        accounting principles to a specific transaction, either completed or
        proposed, or the type of audit opinion that might be rendered on the
        financial statements of the Company as well as any matters or reportable
        events described in Items 304(a)(2)(i) or (ii) of Regulation S-K.
