Exhibit 99.2


                      CHIEF FINANCIAL OFFICER CERTIFICATION


I, Douglas Roth, Chief Financial Officer of Aceto Corporation, certify that:


     1. I have reviewed this Quarterly Report on Form 10-Q of Aceto Corporation
     (the "Registrant");

     2. Based on my knowledge, this Quarterly Report does not contain any untrue
     statement of a material fact or omit to state a material fact necessary to
     make the statements made, in light of the circumstances under which such
     statements were made, not misleading with respect to the period covered by
     this Quarterly Report;

     3. Based on my knowledge, the financial statements, and other financial
     information included in this Quarterly Report, fairly present in all
     material respects the financial condition, results of operations and cash
     flows of the Registrant as of, and for, the periods presented in this
     Quarterly Report;

     4. The Registrant's other certifying officer and I are responsible for
     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules 13a-14 and 15d-14) for the Registrant and have:

     a) designed such disclosure controls and procedures to ensure that material
     information relating to the Registrant, including its consolidated
     subsidiaries, is made known to us by others within those entities,
     particularly during the period in which this Quarterly Report is being
     prepared;

     b) evaluated the effectiveness of the Registrant's disclosure controls and
     procedures as of a date within 90 days prior to the filing date of this
     Quarterly Report (the "Evaluation Date"); and

     c) presented in this Quarterly Report our conclusions about the
     effectiveness of the disclosure controls and procedures based on our
     evaluation as of the Evaluation Date;

     5. The Registrant's other certifying officer and I have disclosed, based on
     our most recent evaluation, to the Registrant's auditors and the audit
     committee of Registrant's board of directors (or persons performing the
     equivalent functions):

     a) all significant deficiencies in the design or operation of internal
     controls which could adversely affect the Registrant's ability to record,
     process, summarize and report financial data and have identified for the
     Registrant's auditors any material weaknesses in internal controls; and

     b) any fraud, whether or not material, that involves management or other
     employees who have a significant role in the Registrant's internal
     controls; and


     6. The Registrant's other certifying officer and I have indicated in this
     Quarterly Report whether there were significant changes in internal
     controls or in other factors that could significantly affect internal
     controls subsequent to the date of our most recent evaluation, including
     any corrective actions with regard to significant deficiencies and material
     weaknesses.
