                              FOR IMMEDIATE RELEASE
                              ---------------------

           ACETO CORPORATION ANNOUNCES FIRST QUARTER FINANCIAL RESULTS

LAKE SUCCESS, NY - November 9, 2005 - Aceto Corporation (NASDAQ:ACET), a global
distributor of chemically-derived pharmaceuticals, biopharmaceuticals, specialty
chemicals and agrochemicals, today announced results of operations for its first
quarter ended September 30, 2005.

Net sales for the first quarter were $75.0 million, compared to $80.4 million in
the first quarter of fiscal year 2005. This decline reflects the previously
disclosed decrease in sales of two active pharmaceutical ingredients (APIs) due
to intense competition. Sales of those two products in the first quarter of
fiscal year 2006 were $1.7 million, compared with $11.8 million in the first
quarter of fiscal year 2005, a decrease of $10.1 million. The gross profit
margin on net sales was essentially unchanged over the two periods. Net income
was $2.0 million, or $0.08 per diluted share, in the first quarter of fiscal
2006, versus $3.4 million, or $0.14 per diluted share, in the same quarter last
year. The decline in net income is largely attributable to the decrease in sales
of the two APIs. (Prior year per share amounts have been adjusted for a 3-for-2
stock split, effected in the form of a dividend, paid January 10, 2005.)

Aceto also announces that it has reached a tentative legal settlement of a
patent claim brought against it that required Aceto to take a charge of $0.5
million in the quarter. This charge reduced first quarter earnings per share by
$0.02 per diluted share and was not anticipated when the Company issued earnings
guidance of at least $0.07 per diluted share for the quarter.

Aceto closed the first quarter in a strong financial position, highlighted by
working capital of $97.6 million, no long-term debt, and shareholders' equity of
$109.8 million at September 30, 2005.

Leonard S. Schwartz, Chairman, CEO, and President of Aceto, stated, "Apart from
the decrease in sales of the two APIs, our business performed well during the
first quarter. Without those two products, our sales grew 7% due primarily to
the introduction of new Health Sciences products, steady growth in our Chemicals
& Colorants segment and strength in our Agrochemicals segment."

Mr. Schwartz added, "We continue to focus on our initiatives in human and
veterinary biopharmaceuticals. Although the FDA no longer plans to issue
guidance before the end of 2005 regarding how approval of human generic
biopharmaceuticals will be handled, we 



firmly believe this market will emerge, and we continue to seek to develop
products and markets in this area. With regard to veterinary biopharmaceuticals,
the USDA is currently reviewing our applications to market a range of vaccines
for companion animals. We hope to commence commercial sales towards the end of
fiscal year 2006, subject to our receiving approvals on a timely basis."

Mr. Schwartz concluded, "In terms of financial guidance, we expect to earn a
minimum of $0.05 per diluted share in the second quarter of fiscal year 2006.
The second quarter results will again reflect reduced sales of the two APIs
mentioned above, which contributed $6.6 million in sales in the second quarter
of fiscal year 2005. The second quarter guidance also includes a $0.01 per
diluted share charge for exiting the facility previously occupied by the
Institutional Sanitary Supplies segment. We remain optimistic about the
long-term strategic direction and prospects of Aceto."
