4-Nitrophenol
4-Nitrophenol, or p-nitrophenol, is a para-nitrated phenol derivative classified under HTS 2908.99.25.00 as 'other nitrophenols.' This pale yellow crystalline solid serves as a key reagent in pharmaceutical synthesis (e.g., paracetamol) and as a pH indicator due to its color change properties.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sulfonated (e.g., nitrophenol sulfonic acids)
Sulfonated derivatives classified earlier in 2908 per Chapter 29 numerical order rule.
If containing heterocyclic nitrogen (e.g., nitro-hydroxyquinolines)
Heterocyclic compounds take precedence over acyclic nitrophenols under later Chapter 29 headings.
If for nitrophenol esters, not free acids
Esters classified with parent acid per note 5(A), but if different function dominates, may shift.

Import Tips & Compliance
• Label with CAS number 100-02-7 and ensure >99% purity certification to distinguish from technical grades
• Comply with EPA TSCA registration; provide end-use declarations to avoid pesticide-related scrutiny
• Watch for dissolution in solvents—if for transport only, remains 2908; specific use formulations may shift to 3824
