Appearance: Colorless to pale pink or brown transparent liquid； Odor: It has a roasted nutty flavor； Other characteristics: Sensitive to air and should be stored in an inert atmosphere or under sealed conditions.; Assay：99%min by GC ; IR Identity: conform to standard ; HNMR： conform to standard ; carbon spectrum: conform to standard ; Water by K. F.:0.5% max or as per the customer’s request ; Loss on drying:0.5% max. or as per the customer’s request ; boiling point: 87-90 ° C (under a pressure of 22 mmHg); =============================================================================== purpose This compound is mainly used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, with specific applications including: Used for synthesizing organic compounds such as 3- (1-methyl-1H-pyrrole-2-yl) propionic acid. As a heterocyclic construction module, it is used for the preparation of pyrrole derivatives in drug development and organic synthesis. In the food industry, its derivatives have been used as flavoring ingredients (JECFA number 2152) =============================================================================== The synthesis path includes: Formylation reaction of N-methylpyrrole: Selective introduction of formyl groups at the 2-position through electrophilic substitution reaction between N-methylpyrrole and formaldehyde or its derivatives (such as trimethoxymethane) under acidic conditions. N-alkylation of 2-pyrrole formaldehyde: 2-pyrrole formaldehyde is first synthesized, and then N-methylated under alkaline conditions using alkylating reagents such as iodomethane. Transition metal catalyzed coupling: In modern synthesis, palladium catalyzed cross coupling strategy may be used to construct pyrrole rings and introduce formyl groups Uses : mainly used as an intermediate in the synthesis of pharmaceuticals and fine chemicals Synonyms : 1-Methylpyrrole-2-carboxaldehyde;1-methylpyrrole-2-carbaldehyde;1-Methyl-1H-pyrrole-2-carbaldehyde;1-Methyl-1H-pyrrole-2-carboxaldehyde; Molecular Structure :
