What Is 4-Aminomethyl-thiophene-2-carbonitrile Hydrochloride?

4-Aminomethyl-thiophene-2-carbonitrile hydrochloride (Aladdin SKU A168395) is an aromatic heterocyclic compound built on a five-membered sulfur-containing thiophene ring. The molecule carries two synthetically important functional groups: a primary aminomethyl group (–CH2NH2) at the 4-position and a nitrile group (–CN) at the 2-position. The compound is supplied as its hydrochloride salt, which confers improved bench stability and aqueous solubility compared with the free base form.

The combination of a nucleophilic amine handle and an electrophilic nitrile within a single, rigid heterocyclic scaffold makes this compound a highly versatile building block. Researchers can exploit the amine for amide coupling, reductive alkylation, Schiff-base formation, or sulfonamide synthesis, while the nitrile can be elaborated into amidines, tetrazoles, or carboxylic acid derivatives under appropriate conditions.

Purity, Specifications, and Quality

Aladdin Scientific supplies A168395 as a research-grade reagent. For confirmed purity grades, batch-specific certificates of analysis (CoA), and analytical data such as HPLC chromatograms, NMR spectra, and mass spectrometry results, customers should refer to the product page on the Aladdin website or contact technical support directly. Lot-specific CoA documents are available upon request.

When evaluating purity requirements for your application, consider that reactions involving the free amine are sensitive to amine content; therefore verifying the assay value and counterion stoichiometry (HCl equivalents) from the CoA before use is recommended. Storage under inert atmosphere and away from moisture will help maintain the declared purity over time.

Handling, Storage, and Safety

As with all primary amine hydrochloride salts containing a nitrile group, standard laboratory precautions should be followed when handling 4-Aminomethyl-thiophene-2-carbonitrile hydrochloride. Personnel should wear appropriate personal protective equipment (PPE), including nitrile gloves, safety goggles, and a laboratory coat. Work should be performed in a well-ventilated area or fume hood.

For storage, the compound should be kept in a tightly sealed container at the temperature recommended on the product label or CoA (commonly 2–8 °C or room temperature under dry conditions for many hydrochloride salts — verify with the specific product documentation). Protect from light, moisture, and incompatible materials. Consult the Safety Data Sheet (SDS) provided by Aladdin Scientific for full hazard classification, first-aid measures, and disposal guidance before use.

Frequently asked questions

What are the primary synthetic uses of 4-Aminomethyl-thiophene-2-carbonitrile hydrochloride?

This compound serves as a bifunctional building block in medicinal chemistry and heterocyclic synthesis. The aminomethyl group can participate in amide bond formation, reductive amination, Schiff-base condensation, and sulfonamide synthesis, while the nitrile group can be converted to amidines, tetrazoles, or carboxylic acids. Together, these handles allow the rapid construction of structurally diverse, drug-like molecules from a single thiophene-based scaffold.

How should I handle the hydrochloride salt form when the free base is required in my reaction?

To liberate the free base, the hydrochloride salt can typically be treated with a mild inorganic base (e.g., aqueous sodium or potassium carbonate) or an organic base (e.g., triethylamine, diisopropylethylamine) prior to or in situ during the reaction. The choice of method depends on the reaction conditions and the sensitivity of other functional groups present. Always verify the free-base conversion by analytical methods such as NMR or titration before use in stoichiometrically sensitive applications.

What storage conditions are recommended for A168395 to maintain compound integrity?

The compound should be stored in a tightly sealed container, protected from moisture, light, and air, at the temperature specified in the product CoA or SDS from Aladdin Scientific. Hydrochloride salts of primary amines are generally hygroscopic, so desiccated storage is advisable. Always consult the batch-specific CoA for the authoritative storage recommendation, and allow cold-stored material to equilibrate to room temperature before opening to prevent condensation.

How do I request a Certificate of Analysis (CoA) or Safety Data Sheet (SDS) for A168395?

CoA and SDS documents for A168395 can be accessed through the Aladdin Scientific product page on the company website by entering the SKU or lot number. Registered customers may also request documents directly through the account management portal or by contacting Aladdin customer support. Lot-specific CoA documents are provided to confirm purity, identity, and analytical test results for each manufactured batch.

Is A168395 suitable for use in biological assays or in vivo studies?

A168395 is supplied as a research-grade synthetic reagent and is intended primarily for use as a chemical building block in laboratory synthesis. It is not formulated or quality-controlled for direct use in biological assays or in vivo applications without further processing and characterization. Researchers planning biological studies should independently assess purity requirements, perform appropriate biocompatibility testing, and consult the SDS for toxicological information.
