Products classified under HTS 2912.19.25.00
Normal Butyraldehyde 99% Pure
Normal butyraldehyde (butanal), the straight-chain isomer, is a colorless volatile liquid used primarily as an intermediate in chemical synthesis for pharmaceuticals and fragrances. It falls under HTS 2912.19.25.00 as an acyclic aldehyde without other oxygen functions, specifically the normal isomer of butanal. This chemically defined organic compound meets Chapter 29 note (a) for separate organic compounds.
Industrial Grade n-Butanal
Industrial grade n-butanal (normal butyraldehyde) is supplied at 97-99% purity for large-scale production of plasticizers and rubber accelerators. Classified under HTS 2912.19.25.00 as the specific normal isomer of butanal, an acyclic aldehyde without other oxygen functions. Stabilizers may be added solely for preservation per Chapter 29 note (f).
Pharma-Grade Butyraldehyde
Pharmaceutical-grade butyraldehyde (normal butanal) meets USP/EP standards for synthesis of active pharmaceutical ingredients like vitamins. It is the chemically defined normal isomer under HTS 2912.19.25.00, acyclic aldehyde without other oxygen function. Low impurity levels ensure compliance with Chapter 29 purity requirements.
Butanal with 0.1% Hydroquinone Stabilizer
Normal butanal stabilized with 0.1% hydroquinone to prevent polymerization during storage and transport. Remains classified as pure butanal under HTS 2912.19.25.00 since stabilizer is necessary for preservation per Chapter 29 note (f). Used in flavor/fragrance synthesis.
Distilled n-Butyraldehyde 98.5%
High-purity distilled n-butyraldehyde at 98.5% concentration, fractionally distilled to remove iso-butanal impurities. Specifically the normal isomer under HTS 2912.19.25.00 as acyclic aldehyde without other oxygen function. Essential for high-value polymer precursor synthesis.
Butyraldehyde for Plasticizer Production
Technical grade normal butyraldehyde dedicated for 2-ethylhexanol production used in DOP plasticizers. Pure normal isomer qualifies for HTS 2912.19.25.00 as acyclic aldehyde without other oxygen function. Meets Chapter 29 requirements for chemically defined compounds.
