              ACETO CORPORATION REPORTS SECOND QUARTER RESULTS WITH
                     BEST EVER QUARTERLY GROSS PROFIT MARGIN

LAKE SUCCESS, NY - February 11, 2004 - Aceto Corporation (Nasdaq:ACET), a global
distributor of pharmaceutical and specialty chemicals, today announced quarterly
results of operations for its second quarter and six months ended December 31,
2003. The operating results do not reflect the Company's acquisition of Pharma
Waldhof, which was consummated on December 31, 2003.

SECOND QUARTER FINANCIAL HIGHLIGHTS - versus fiscal 2003 second quarter
o    Net sales grew 7% to $69.2 million.
o    Gross profit rose 18% to $12.9 million.
o    Net income increased 27% to $3.0 million or $0.19 per diluted share, from
     $2.3 million or $0.16 per diluted share in the same period last year. The
     weighted average number of diluted shares outstanding rose 7% due to an
     increased number of stock options exercised during the past year and
     because more unexercised stock options were included in the calculation as
     a result of the Company's higher stock price.

SIX-MONTH FINANCIAL HIGHLIGHTS - versus the first six months of fiscal 2003
o    Net sales were up 7% to $141.5 million.
o    Gross profit grew 14% to $25.3 million.
o    Income, before the cumulative effect of a non-cash accounting charge of
     $1.9 million in last year's period, increased 31% to $6.1 million or $0.38
     per diluted share, from $4.7 million or $0.31 per diluted share in the
     first six months of fiscal 2003. For the reasons set forth above, the
     weighted average number of diluted shares outstanding increased 8.5%.

Leonard S. Schwartz, Chairman, CEO and President of Aceto, stated, "We are
pleased with the results for the second quarter and first half of fiscal 2004,
during which our three main business segments - Health Sciences, Chemicals and
Colorants, and Agrochemicals - all performed well. Our gross profit margin rose
from 17.0% in the second quarter of last year to 18.7% in the current period,
representing our best-ever quarterly gross profit margin. We are especially
encouraged because these results were achieved despite no new product launches
in our Health Sciences segment in the quarter. We do, however, expect to launch
at least three Active Pharmaceutical Ingredients (APIs) during the second half
of the year."

Douglas Roth, CFO of Aceto, added, "In the second quarter, SG&A expenses
increased, as expected, from $7.7 million to $9.3 million primarily due to
higher professional fees related to internal control documentation and
assessment as mandated by the Sarbanes-Oxley legislation, and non-recurring
legal fees connected with a fully successful lawsuit in China and our joint
venture with Nufarm. Additionally, SG&A was negatively impacted by currency
translation from Euros to US dollars which was more than offset by the
favorable currency translation for sales and gross profit."

Mr. Roth continued, "Our financial position remains strong. As of December 31,
2003, we had cash of $31.9 million, working capital of $77.3 million, no
long-term debt and shareholders' equity of $93.2 million."

Mr. Schwartz further stated, "We recently completed the acquisition of Pharma
Waldhof from Roche and are extremely enthusiastic about the addition of this
biopharmaceutical distribution company to our business. Not only do we believe
the transaction will be immediately accretive to earnings, but it serves as the
cornerstone of Aceto's entry into the biopharmaceutical market and positions us
on the cutting edge of the generic biopharmaceutical market as it develops.
Another emerging market in which we are excited to be participating is Eastern
Europe, which, prior to entry into the EU, is mostly unregulated in terms of
pharmaceuticals. We opened an office in Poland in early January to facilitate
the supply of EU-approved APIs to pharmaceutical manufacturers in countries
joining the EU, such as Poland, where the EU pharmaceutical standards will be
required under the law by June of this year."

Mr. Schwartz concluded, "As a result of these recent developments and the
strength of our ongoing business, we are optimistic about Aceto's near and
long-term prospects. Current initiatives for continued growth include launching
products from our pipeline of over 50 APIs, establishing another business
location in Eastern Europe, and pursuing additional agrochemical partnerships
and product acquisitions. We are seeing more and more agrochemical opportunities
due to the consolidation of large companies and the disintermediation of the
traditional supply channels. With regard to financial guidance for the third
quarter of fiscal 2004, we anticipate achieving earnings of $0.19 - $0.22 per
diluted share, which compares to $0.16 in the third quarter of last year. We
look forward to updating you with our progress."
