Products classified under HTS 2918.30.10.00
Methyl 2-(4-Formylphenyl)acetate
This is the methyl ester of 4-formylphenylacetic acid, a chemically defined aromatic carboxylic acid with both aldehyde and ester oxygen functions. It falls under HTS 2918.30.10.00 as it precisely matches the description of 1-formylphenylacetic acid, methyl ester, which is a specific compound in the subcategory of aromatic carboxylic acids with aldehyde function. Primarily used as an intermediate in pharmaceutical synthesis.
4-Formylphenylacetic Acid Methyl Ester USP Grade
High-purity USP grade version of 1-formylphenylacetic acid methyl ester, meeting pharmaceutical standards for use in drug intermediate synthesis. Classified under HTS 2918.30.10.00 due to its exact chemical identity as the specified aromatic compound with aldehyde and ester functions. The USP designation confirms it's a separate chemically defined organic compound per Chapter 29 notes.
p-Formylphenylacetic Acid Methyl Ester Technical Grade
Technical grade 1-formylphenylacetic acid methyl ester used in chemical manufacturing and research, with typical purity of 98%+. This specific aromatic compound with formyl and methyl ester groups on phenylacetic acid backbone is explicitly named in HTS 2918.30.10.00. Meets Chapter 29 criteria for separate chemically defined compounds, even with minor impurities.
2-(4-Formylphenyl)acetic Acid Methyl Ester
Synonymous chemical name for the HTS-specified 1-formylphenylacetic acid methyl ester, an aromatic polyketone precursor in organic synthesis. Classified precisely under 2918.30.10.00 as it matches the legal description of carboxylic acids with aldehyde function. Used in fine chemical production for fragrances and pharmaceuticals.
CAS 70288-50-1 Methyl 4-Formylphenylacetate
Identified by CAS number 70288-50-1, this is the pure methyl ester of 4-formylphenylacetic acid matching HTS 2918.30.10.00 exactly. As a separate chemically defined aromatic compound with dual oxygen functions (aldehyde and ester), it fits Chapter 29 subheading for specific named substances. Commonly traded for API synthesis.
