What 1-bromododecane is
Compared with short-chain bromides such as 1-bromobutane, 1-bromododecane carries a twelve-carbon tail. That chain length is the reason it is widely used to introduce a dodecyl group into amines, quaternary ammonium salts, and specialty intermediates. Buyers should order by CAS 143-15-7, not by a vague "lauryl bromide," so isomer and chain-length distribution stay under control.
Main uses
The first use is surfactant manufacture. 1-Bromododecane CAS 143-15-7 is a raw material for dodecyl-substituted surfactants and related amphiphiles. The C12 chain is a common hydrophobe in detergents, fabric conditioners, and industrial surfactant packages.
The second use is pharmaceutical and fine-chemical alkylation. Medicinal and process chemists use 1-bromododecane when a lipophilic C12 side chain is required on a nitrogen or oxygen center. It remains an intermediate, not an API.
The third use is general organic synthesis and, in some applications, as a specialty solvent. In all cases, the purchasing decision is driven by assay, color, water, and residual acidity, because these parameters affect both alkylation yield and odor in downstream products.
Typical properties and packing
A working specification for 1-bromododecane CAS 143-15-7 includes molecular formula C12H25Br, EINECS 205-587-9, melting point about −11 to −9°C, boiling point 134–135°C (as listed on the product file), density about 1.040 g/mL, and purity ≥99%. Appearance should be a colorless transparent liquid. Packing options include 1 L bottles, 25 L drums, 200 L drums, and 1000 L IBC drums, or customer packing. Sealed storage typically supports a 24-month shelf life.
Storage, handling, and QC
Store 1-bromododecane in a cool, dry, well-ventilated place with the container tightly closed, away from light and moisture. Some users keep it at room temperature; others prefer 2–8°C for long holds. It can irritate skin, eyes, and the respiratory tract (GHS signal word Warning in many files). Use gloves, eye/face protection, and good ventilation, and avoid breathing vapors. Do not discharge to drains. Absorb spills with inert material and send as hazardous waste. Incoming QC should confirm identity, assay, color, and water against the COA for the drum on the floor.
Why buyers source from Arise New Material
Arise New Material supplies 1-bromododecane among organic chemicals, with samples for route trials and documents (COA, MSDS, invoice, packing list) for export. Small orders can move by express or air; bulk lots can go by sea.
If you are locking a C12 alkylating agent for surfactant or pharmaceutical intermediate work, ask Shanghai Arise New Material Co., Ltd. for a sample and COA of 1-bromododecane CAS 143-15-7. Share your next step (quat, amine alkylation, or surfactant) so packing and assay can match the process.
