{"product_id":"methyl-3-formylindole-5-carboxylate-2pk7-2pk7","title":"Methyl-3-Formylindole-5-carboxylate, min. 90 %, 1 g","description":"\u003cp\u003eMethyl-3-formylindole-5-carboxylate is an indole-based organic building block supplied at a minimum purity of 90 % for laboratory and biochemical work. It is identified by CAS number 197506-83-5 and the empirical formula C₁₁H₉NO₃, with a molar mass of 203,19 g\/mol. This compact aromatic ester–aldehyde combines a formyl group at the 3-position with a methyl carboxylate at the 5-position of the indole core, giving a defined molecular handle for further synthetic elaboration. The material is Physical and identity data from manufacturer Carl ROTH support straightforward documentation in research notebooks and inventory systems. As a specialised biochemical intermediate, it fits workflows that require a characterised indole carboxylate of known molar mass and CAS registry entry. The stated minimum assay of 90 % provides a clear quality baseline for screening and exploratory synthesis without overstating grade claims. Researchers can integrate the compound into multi-step sequences where both the aldehyde and ester functionalities are of interest, while relying on the listed formula and molar mass for stoichiometric calculations.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-nl\/collections\/dehydrated-culture-media\"\u003eDehydrated culture media (agar \u0026amp; broth bases)\u003c\/a\u003e, in \u003ca href=\"\/en-nl\/collections\/culture-media-and-microbiology\"\u003eCulture media \u0026amp; microbiology\u003c\/a\u003e.
