Para Nitrobenzamide

Para Nitrobenzamide (4-nitrobenzamide) is the simple amide of the carboxylic acid elsewhere in this part of our range — install an ammonia-derived amide group in place of the acid's hydroxyl, and the nitro group's position and reactivity carry straight through unchanged. We want to flag upfront that several of the physical constants we could find for this specific compound — boiling point and density in particular — were explicitly labelled by the source as estimated or calculated values, not measured ones, and the melting point we found rests on a single source we could not independently cross-verify. We present these figures with that caveat rather than implying a precision the underlying data doesn't support.

Its documented use is as a precursor in fine-chemical and pharmaceutical intermediate synthesis generally — one source specifically names its use in preparing 4-nitrobenziminosulfurane, a specialty synthetic reagent. The straightforward expectation that it serves as a precursor to 4-aminobenzamide by nitro-group reduction is standard, well-understood chemistry, though we did not find this specific transformation explicitly documented for this compound in the sources we checked, so we present it as expected chemistry rather than a confirmed, sourced use. We looked specifically for a liquid-crystal application sometimes claimed for compounds in this general class and could not independently confirm one for this specific compound — we don't repeat that claim here.

Where it fits in the synthesis chain

We supply Para Nitrobenzamide itself, as a fine-chemical and pharmaceutical intermediate.

Grades we supply

97% and 98% grades are both seen across the trade.

The standard, chemically expected route to Para Nitrobenzamide is amidation of 4-nitrobenzoyl chloride, or of methyl 4-nitrobenzoate, with ammonia — converting the activated acid derivative directly to the amide.

We want to be honest that we did not find this exact route explicitly documented in a primary source for this specific compound during this research pass — it is textbook amide-formation chemistry, consistent with how this compound is named and sold alongside its corresponding acid, but we present it as the expected route rather than an independently sourced one.

The crude product is purified by crystallisation and dried to the finished white powder, tested for residual starting material and moisture before release.

Being honest about data quality on this specific product

We'd rather tell you plainly that this compound's physical-property data is thinner than for most products in our catalogue. The melting point rests on a single source; the boiling point and density figures are both explicitly labelled estimates by the source that reported them, not measured values. We publish them because they're the best available figures, but we recommend treating the certificate of analysis for your specific batch, not this page's specification rail, as the governing reference for anything precision-sensitive.
