3-Acetoxy-4-methylbenzoic Acid CAS 17477-46-2

Identity and specification

3-Acetoxy-4-methylbenzoic Acid is also named 3-(acetyloxy)-4-methylbenzoic acid. The acetoxy group is at position 3 and the methyl group at position 4. CAS 17477-46-2, the substitution pattern and formula C10H10O4 should agree across the specification, COA and label.

Quality controls for purchasing

• Confirm the positional isomer by suitable chromatography and spectroscopy rather than relying on assay alone.
• Control the corresponding hydroxy acid because the acetoxy group can hydrolyze during processing or storage.
• Set limits for water, residual solvents, melting range, color, known route impurities and unknown related substances.

Applications and grade selection

This aromatic acid may be evaluated as a fine-chemical or pharmaceutical-intermediate building block. Its utility depends on substitution pattern and protection-state integrity. Sample testing should confirm reaction conversion, hydrolysis behavior, downstream impurity clearance and isolated product quality.

Storage and handling

Store tightly sealed in a cool, dry place protected from moisture and excessive heat to limit hydrolysis. Segregate from strong bases and oxidizers, preserve the original identification label and follow the supplier SDS for handling and disposal.

Documentation and quotation details

Include the exact substitution pattern, CAS, assay, hydroxy-acid limit, positional-isomer controls, water, residual-solvent limits, quantity, packaging and destination in the inquiry. Request a representative COA, SDS and sample for route qualification.
