3'-Chloroacetophenone (CAS 99-02-5) is a ring-chlorinated aryl ketone used as a synthetic building block and intermediate in organic, pharmaceutical and fine-chemical synthesis. For example, it serves as a substrate for asymmetric reduction to chiral 1-(3-chlorophenyl)ethanol and for condensations with aromatic aldehydes to form chalcones. This solid compound has a molecular formula of ClC6H4COCH3 and a molecular weight of 154.59 g/mol. It should be stored at ambient temperatures, handled with care (Signal Word: Warning), and disposed of according to local regulations. Molekula supplies 3'-Chloroacetophenone from research to bulk quantities with full documentation and ISO 9001:2015 traceability.

Frequently asked questions
What is 3'-Chloroacetophenone (99-02-5) commonly used for?
3'-Chloroacetophenone is used as a chemical intermediate and building block in organic and pharmaceutical synthesis, for example as a substrate for asymmetric reduction to chiral 1-(3-chlorophenyl)ethanol and in condensations to prepare chalcones. It is not a tear gas agent, which is 2-chloroacetophenone (CN, CAS 532-27-4), where the chlorine is on the methyl carbon rather than the aromatic ring.
What is the chemical formula and molecular weight of 3'-Chloroacetophenone?
The chemical formula is **ClC₆H₄COCH₃**, and the molecular weight is **154.59 g/mol**.
How should 3'-Chloroacetophenone be stored?
Store in a **cool, dry place at ambient temperature**, away from incompatible substances, and ensure proper ventilation to avoid inhalation exposure.
What grades or purities of 3'-Chloroacetophenone does Molekula supply?
Molekula supplies **high-purity (98%+ analytical grade)** 3'-Chloroacetophenone; please contact us for bulk or custom specifications.
Can Molekula supply 3'-Chloroacetophenone in bulk quantities?
Yes, we offer **bulk quantities** of 3'-Chloroacetophenone; minimum order quantities and pricing depend on the specific application and regulatory requirements.
What documentation comes with an order of 3'-Chloroacetophenone?
Each order includes a **Certificate of Analysis (CoA)**, Material Safety Data Sheet (MSDS/SDS), and compliance documentation for regulatory requirements (e.g., REACH, OSHA).
