Pharmaceutical and Agrochemical Intermediates
Where a synthesis route names a specific halide, aldehyde or alcohol, Dakings supplies that compound with its CAS number, GC assay and moisture figure — the three numbers a process chemist checks before releasing the drum to the reactor.
What This Industry Struggles With
- Water in a halide kills Grignard initiation and quenches the batch
- An intermediate without a named CAS on the document set fails goods-in QA
- Route qualification is expensive, so mid-campaign supplier changes are avoided
- Small colour or assay drift shows up as impurity profile changes in the API
What we bring to it
- CAS number, molecular formula and molecular weight stated on every product page
- Moisture specified by Karl Fischer where the chemistry is water sensitive
- 175-180 kg drums or tank truck, packed to your handling procedure
Where Our Material Goes in Your Process
Grignard reagent preparation
1-Bromopropane and 2-bromopropane are both used as Grignard raw materials, 1-bromopropane also as an alkylating agent for aromatic compounds.
Named API intermediates
1-Bromopropane is an intermediate for prothiamine and probenecid. 1-Propanol feeds probenecid, adhesive haemostatic agent BCA, propylthiamine and 2,5-pyridinedicarboxylate propyl ester.
Crop protection
2-Bromopropane is used in the manufacture of napropamide. 1-Propanol is the raw material for n-propylamine and di-n-propylamine.
Four carbon chain building
1,4-Dichlorobutane is used as raw material and solvent for organic synthesis, including adiponitrile and carboxymethyl drug routes.
Aldehyde chemistry
Propionaldehyde is the basic raw material for n-propanol, propionic acid, dimethylol propionic acid for waterborne polyurethane, methyl methacrylate and trimethylol ethane.

Where the Pentanol Mixture Is Actually Used
A multifunctional solvent used across coatings, inks, pigments, cleaning agents, flavours and organic synthesis, with a documented isomer split.
Process GuideProduction Methods and Main Applications of Propionaldehyde
Low-pressure oxo synthesis became the dominant propionaldehyde route from the 1970s and today accounts for the overwhelming share of capacity.
Pharmaceutical and Agrochemical Intermediates Questions
Do you provide SDS and COA for intermediates?
Yes, SDS and COA are available for these products. Ask for the current lot documents before you place the order so your QA can review the assay and moisture first.
What assay does 1,4-dichlorobutane carry?
99.59% minimum by GC with moisture at 0.059% maximum, supplied as a clear colourless liquid in 180 kg drums or by tank truck.
Is your 2-propanol suitable for nucleic acid work?
2-Propanol is used for nucleic acid precipitation, where roughly half the volume of ethanol is needed. Our superior grade runs 99.9% minimum isopropyl alcohol with 10 maximum Pt-Co colour and 0.10% maximum water; the measured lot reported 99.96%.
Can you hold stock against a campaign schedule?
