1-Bromopentane NEW

Product Parameters

1-Bromopentane (n-Amyl bromide) CAS No.: 110-53-2,Molecular formula: C5H11Br,M.W.: 151.05, is a colourless to slight yellow clear liquid.1-Bromopentane is a medium-chain alkyl bromide that combines favourable lipophilicity with a well-balanced reactivity profile. The compound is recognised as a high-performance pentylating agent, enabling the reliable, regioselective introduction of the n-pentyl group into a broad range of organic substrates. It therefore serves as a versatile building block for the construction of functional molecules across pharmaceutical, agrochemical, fragrance, dye and advanced-material sectors.

Specifications & Quality Control

We provide high-purity bromopentane with a standard specification of ≥ 99.0% (GC). Through strict distillation process and process quality control, the product has the characteristics of low color (APHA), low moisture (determined by Karl Fischer method), low acid value, and low impurity content, ensuring excellent reaction efficiency and product purity guarantee for key reactions such as nucleophilic substitution. Its excellent batch consistency meets the full process requirements from laboratory research and development to industrial production.

Main Applications

1-Bromopentane is an important fine chemical intermediate with a wide range of applications, including:

Pharmaceutical & Agrochemical Intermediates:

As key building blocks, used for synthesizing a series of drug molecules (such as sedatives and hypnotics) and highly efficient and low toxicity pesticides, introducing pentyl chains to regulate biological activity.

Fragrance & Dye Chemistry:

Used for synthesizing spice compounds with fruity and alcoholic aromas, as well as dye intermediates with specific structures.

Functional Materials & Surfactants:

As a precursor, it is used to prepare special surfactants, functional polymer materials, and solvents and reagents in organic synthesis.

R&D & Experiment:

Routinely employed in academic and industrial laboratories for method-development, route-scouting and scale-up studies.

Use, Storage & Safety Guidelines
This product is recommended to be operated in a well ventilated environment. It is recommended to conduct the reaction under alkaline catalysis or inert gas protection, and avoid contact with strong oxidants. When storing, it should be sealed, away from light, and placed in a cool and dry place.Operators must wear chemically resistant gloves, goggles, and impervious clothing; prevent inhalation of vapours and avoid contact with skin or eyes. Consult and follow the latest revision of the MSDS supplied with each shipment for comprehensive handling, first-aid, and transport procedures before use.

Packaging, Logistics & Technical Services

We offer flexible packaging solutions: industrial-grade products in 250 kg drums, plus laboratory sizes of 100 ml and 500 ml reagent bottles. Each shipment is accompanied by a Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS), and third-party test reports can be provided on request. A dedicated technical-support team is available for application advice, process optimization, and any other assistance you may need.
