                  ACETO CORPORATION REPORTS BEST EVER QUARTERLY
                                    RESULTS

LAKE SUCCESS, NY - November 6, 2003 - Aceto Corporation (Nasdaq:ACET), a global
distributor of pharmaceutical and specialty chemicals, today announced record
quarterly results of operations for its first quarter ended September 30, 2003.

FIRST QUARTER FINANCIAL HIGHLIGHTS - versus fiscal 2003 first quarter

     o    Net sales rose 6% to $72.3 million.
     o    Operating income grew 17% to $4.2 million.
     o    Income, before the cumulative effect of a non-cash accounting charge
          of $1.9 million in the first quarter of last year, increased 34% to
          $3.1 million or $0.29 per diluted share, from $2.3 million or $0.24
          per diluted share in the same period last year.

Leonard S. Schwartz, Chairman, CEO and President of Aceto, stated, "We are
pleased to report our best quarter ever in terms of sales and net income, during
which our Health Sciences segment launched one new Active Pharmaceutical
Ingredient (API), and three smaller volume products to the generic
pharmaceutical industry. We define a product launch as a launch in which we
expect to realize more than $2 million in sales during the six-month launch
period. Additionally, our existing generic pharmaceutical business showed
continued strength.

"In addition, we achieved sales, gross profit, and gross profit margin increases
in our three main business segments - Health Sciences, Chemicals and Colorants,
and Agrochemicals - which together generated an overall gross profit margin of
17.04%, versus 16.53% in the first quarter of last year. SG&A expenses, net of a
$300,000 non-recurring gain from the sale of property in last year's period,
remained essentially flat as a percent of net sales, producing a 34% increase in
income, before the cumulative effect of a non-cash accounting charge, on a 6%
sales increase."

Mr. Schwartz further stated, "In addition to focusing on organic growth in our
core businesses and our Health Sciences segment's plans to launch at least four
Active Pharmaceutical Ingredients (APIs) per year, we are pursuing other avenues
for continued growth. As recently announced, we signed a letter of intent to
form a joint venture with Nufarm Limited to market a herbicide that we presently
market under a different label. This partnership reflects our strategy to
capitalize on the consolidation and impending disintermediation of traditional
supply channels in the agrochemical



industry by forming alliances with major agrochemical companies. We expect to
formally commence the joint venture within two weeks.

"We also announced plans to expand our presence in Eastern Europe to facilitate
the supply of European Union-approved APIs to pharmaceutical manufacturers in
countries that will soon join the EU. Through our new office in Poland, which
will enhance and expand upon our existing business in that region, which is
currently serviced by our Hamburg office, we will continue to provide
comprehensive technical, regulatory and quality control support to the Eastern
European market of 120 million people, which is presently unregulated in terms
of pharmaceuticals. Additionally, we are in active discussions to establish
another business location in Eastern Europe."

Mr. Schwartz continued, "Most recently, we signed a letter of intent to acquire
a biopharmaceutical distribution company with 2002 sales in excess of $10
million. We are enthusiastic about this potential acquisition, which would
represent Aceto's entree into the rapidly growing biopharmaceuticals market and
would position the Company to participate in the generic biopharmaceutical
business, which is in its infancy. The proposed acquisition, if completed, would
be immediately accretive to our earnings and would broaden our product offerings
to the pharmaceutical industry. We anticipate the closing to take place on or
about December 31, 2003.

Douglas Roth, CFO of Aceto, added, "With regard to the Company's financial
position, as of September 30, 2003, we had working capital of $75.7 million, no
long-term debt and shareholders' equity of $88.4 million. Our financial strength
and flexibility forms a solid foundation to support our growth endeavors."

Mr. Schwartz continued, "We have revised our guidance policy to now include
expected product launches. In this regard, for the second quarter of fiscal
2004, we anticipate earning $0.25 - $0.30 per diluted share, which compares to
$0.23 per diluted share in the second quarter of last year. "

Mr. Schwartz concluded, "We remain focused on utilizing our sourcing and
regulatory strengths, as well as our unique worldwide distribution capabilities
to pursue continued growth. We are optimistic about Aceto's short and long-term
prospects, and look forward to updating you with our progress."
