               ACETO CORPORATION ANNOUNCES SECOND QUARTER RESULTS
                                WITH SALES UP 12%

LAKE SUCCESS, NY - February 3, 2005 - Aceto Corporation (Nasdaq:ACET), a global
distributor of chemically-derived pharmaceuticals, biopharmaceuticals, specialty
chemicals and agrochemicals, today announced quarterly results of operations for
its fiscal 2005 second quarter and six months ended December 31, 2004.

For the second quarter, net sales increased 12% to $75.8 million, from $68.0
million in the second quarter of fiscal 2004. Gross profit increased 5% to $13.0
million from $12.3 million. Income from continuing operations was $2.5 million
or $0.10 per diluted share, compared to $3.2 million or $0.13 per diluted share
in the second quarter of last year. Net income was $2.0 million or $0.08 per
diluted share, versus $3.0 million or $0.12 per diluted share in the second
quarter of last year. Net income for the second quarter included losses from
discontinued operations of $0.5 million and $0.2 million in the 2005 and 2004
periods, respectively, net of income tax benefits, related to the Company's
planned sale of its Institutional Sanitary Supplies segment. The loss from
discontinued operations includes a non-cash impairment charge of $0.4 million,
net of income tax benefit, in the second quarter of fiscal 2005. (All per share
amounts have been adjusted for the January 10, 2005 3-for-2 stock split effected
in the form of a dividend.)

Net sales for the six months ended December 31, 2004 increased 12% to $155.2
million from $138.9 million in the same period of the prior year. Net income was
$5.3 million or $0.22 per diluted share for the first six months of fiscal 2005,
which included the aforementioned non-cash impairment charge of $0.4 million, as
compared to net income of $6.1 million or $0.25 per diluted share in the same
period of fiscal 2004.

Second quarter earnings from continuing operations were impacted by several
factors:

1)   The Company experienced significant competitive pricing on two of its
     important, mature, chemical-based APIs that it sells to European customers,
     and accordingly lowered the price to maintain the business. This negatively
     impacted gross profit by $0.4 million. The Company does not expect to
     return to the higher pricing in the near-term.

2)   Aceto encountered a production issue with a Chinese supplier regarding one
     generic pharmaceutical product that the Company had not supplied since its
     initial launch two years ago. As a result, Aceto's producer had
     substantially scaled down production to a level to satisfy only the Chinese
     market. The Company's customer had the opportunity to essentially re-launch
     the product and placed a large order for delivery principally in the first
     and second quarters of fiscal 2005, with a small amount to be delivered in
     the third quarter. In scaling up production, delays unfortunately occurred.
     Such delays are not uncommon in fine chemical and pharmaceutical
     production, and Aceto was able to ship only a limited amount in its second
     quarter. This impacted second quarter gross profit by $0.1 million. The
     balance of the order will likely be delivered in the third fiscal quarter.

3)   The Company incurred a bad debt expense of $0.2 million in the current
     quarter as compared to a net recovery of $0.1 million in the comparable
     period last year.

4)   Selling, general and administrative expenses ("SG&A") increased to $9.6
     million in the second quarter of 2005 compared to $8.4 million in the
     second quarter of 2004. SG&A increased primarily due to the inclusion of
     Aceto's Pharma Waldhof business, which was acquired in December 2003 and
     added $0.6 million in expenses, a higher provision for bad debts as
     discussed above and $0.3 million of costs associated with the Company's
     Strategic Business Initiatives. The Company is taking steps to limit its
     SG&A without adversely affecting ongoing and future business prospects.

Leonard S. Schwartz, Chairman, CEO and President of Aceto, stated, "While
certain factors outlined above are impacting the level of our current
profitability, we are not letting this diminish the efforts and energies that we
are putting into our Strategic Business Initiatives. We fully expect the success
of these initiatives will propel Aceto to a new, higher level in the future.
Most significant is our Biopharmaceutical Initiative, which now encompasses the
key components of the biopharmaceutical market: patented products for humans,
the emerging generic market, specialty vaccines for humans, and a segment of the
veterinary market. We have identified and are targeting certain products for
which regulatory pathways already exist. I will be presenting our
Biopharmaceutical Initiative in greater detail at the upcoming UBS Healthcare
Services Conference on February 16th in New York."

Mr. Schwartz continued, "We are also leveraging our successful trials of
Landfill Odorend. We launched a very aggressive marketing campaign in early
January immediately after completing our technical and regulatory support work.
It is aimed at landfills in our target market areas, namely major
waste-management companies and governmental agencies responsible for the
regulation of landfills. One major landfill in the Northeast with a significant
odor problem has agreed to conduct a commercial-scale trial. A technical report
about Landfill Odorend is available upon request."

"Our three other Strategic Business Initiatives (expansion of our Agrochemicals
business, organic color pigments, and development of business in Eastern Europe)
are all going well and already beginning to provide revenues to the Company.

"We acquired office space in a building under construction in Shanghai, which
will be completed next month. The new facility provides significant room for
growth in China to support our business and technical activities and at the same
time sends a strong signal to the Chinese market and government that Aceto
continues to expand and maintain its commitment to China. Our staff in China is
expected to increase from 24 to 28 people to support the growing business in the
region. All of our Strategic Business Initiatives will be discussed during our
conference call this morning."

Mr. Schwartz concluded, "Our strong financial position serves as a solid
foundation to support these initiatives. At December 31, 2004, we had working
capital of $91.7 million, no long-term debt and shareholders' equity of $106.8
million. In terms of financial guidance, due to continued competitive pricing
mentioned earlier and higher expenses related to new business initiatives, we
anticipate earnings of approximately $0.09 - $0.11 per diluted share in the
third quarter. Again, we remain very optimistic about the Company's long-term
business prospects."
